Any business putting "privacy first" thing that works only on their server, and requires full access to plaintext data to operate, should be seen as lying.

I've been annoyed by proton for a long while; they do (did?) provide a seemingly adequate service, but claims like "your mails are safe" when they obviously had to have them in plaintext on their server, even if only for compatibility with current standards, kept me away from them.

We're still in the "IT'S GETTING BILLIONS IN INVESTMENTS" part. Can't wait for this to run out too.

It's probably different. The crypto bubble couldn't actually do much in the field of useful things.

Now, I'm saying that with a HUGE grain of salt, but there are decent application with LLM (let's not call that AI). Unfortunately, these usages are not really in the sight of any business putting tons of money into their "AI" offers.

I kinda hope we'll get better LLM hardware to operate privately, using ethically sourced models, because some stuff is really neat. But that's not the push they're going for for now. Fortunately, we can already sort of do that, although the source of many publicly available models is currently… not that great.

Does it even count as enshittifying if they were born that way?

It was Snowball! He wrote the article! Must have been!

they obviously had to have them in plaintext on their server, even if only for compatibility with current standards

I don’t think that’s obvious at all. On the contrary, that’s a pretty bold claim to make, do you have any evidence that they’re doing this?

How have they enshittified? I haven’t noticed anything about their service get worse since they started.

Incoming Emails that aren't from proton, or PGP encrypted (which are like 99% of emails), arrives at Proton Servers via TLS which they decrypt and then have the full plaintext. This is not some conspiracy, this is just how email works.

Now, Proton and various other "encrypted email" services then take that plaintext and encypt it with your public key, then store the ciphertext on their servers, and then they're supposed to discard the plaintext, so that in case of a future court order, they wouldn't have the plaintext anymore.

But you can't be certain if they are lying, since they do necessarily have to have access to the plaintext for email to function. So "we can't read your emails" comes with a huge asterisk, it onlu applies to those sent between Proton accounts or other PGP encrypted emails, your average bank statement and tax forms are all accessible by Proton (you're only relying on their promise to not read it).

Ok yeah thats a far cry from Proton actually “Having your unencrypted emails on their servers” as if they’re not encrypted at rest.

There’s the standard layer of trust you need to have in a third party when you’re not self hosting. Proton has proven so far that they do in fact encrypt your emails and haven’t given any up to authorities when ordered to so I’m not sure where the issue is. I thought they were caught not encrypting them or something.

The law isn't a law yet, its a just a proposal. Proton is still in Switzerland, but they said they're gonna move if the surveillance law actually becomes law.

There's absolutely a push for specialized hardware, look up that company called Groq !

I think it's different. The fundamental operation of all these models is multiplying big matrices of numbers together. GPUs are already optimised for this. Crypto was trying to make the algorithm fit the GPU rather than it being a natural fit.

With FPGAs you take a 10x loss in clock speed but can have precisely the algorithm you want. ASICs then give you the clock speed back.

GPUs are already ASICS that implement the ideal operation for ML/AI, so FPGAs would be a backwards step.

Yes, but at this point most specialized hardware only really work for inference. Most players are training on NVIDIA GPUs, with the primary exception of Google who has their own TPUs, but even these have limitations compared to GPUs (certain kinds of memory accesses are intractably slow, making them unable to work well for methods like instant NGP).

GPUs are already quite good, especially with things like tensor cores.

LLMs are absolutely amazing for a lot of things. I use it at work all the time to check code blocks or remembering syntax. It is NOT and should NOT be your main source of general information and we collectively have to realise how problematic and energy consuming they are.

First of all...

Why does an email service need a chatbot, even for business? Is it an enhanced search over your emails or something? Like, what does it do that any old chatbot wouldn't?

EDIT: Apparently nothing. It's just a generic Open Web UI frontend with Proton branding, a no-logs (but not E2E) promise, and kinda old 12B-32B class models, possibly finetuned on Proton documentation (or maybe just a branded system prompt). But they don't use any kind of RAG as far as I can tell.

There are about a bajillion of these, and one could host the same thing inside docker in like 10 minutes.

OK, so I just checked the page:

Lumo: Privacy-first AI assistant where chats stay confidential

Meet Lumo, the zero-access encrypted AI assistant by Proton that does not track or record your conversations. Ask me anything — it's confidential

(lumo.proton.me)

Looks like a generic Open Web UI instance, much like Qwen's: https://openwebui.com/

Based on this support page, they are using open models and possibly finetuning them:

Lumo privacy | Proton

Lumo by Proton is designed to protect your data. Learn more about our no-logs policy, zero-access encryption, and other safeguards.

Proton (proton.me)

The models we’re using currently are Nemo, OpenHands 32B, OLMO 2 32B, and Mistral Small 3

But this information is hard to find, and they aren't particularly smart models, even for 32B-class ones.

Still... the author is incorrect, they specify how long requests are kept:

When you chat with Lumo, your questions are sent to our servers using TLS encryption. After Lumo processes your query and generates a response, the data is erased. The only record of the conversation is on your device if you’re using a Free or Plus plan. If you’re using Lumo as a Guest, your conversation is erased at the end of each session. Our no-logs policy ensures wekeep no logs of what you ask, or what Lumo replies. Your chats can’t be seen, shared, or used to profile you.

But it also mentions that, as is a necessity now, they are decrypted on the GPU servers for processing. Theoretically they could hack the input/output layers and the tokenizer into a pseudo E2E encryption scheme, but I haven't heard of anyone doing this yet... And it would probably be incompatible with their serving framework (likely vllm) without some crack CUDA and Rust engineers (as you'd need to scramble the text and tokenize/detokenize it uniquely for scrambled LLM outer layers for each request).

They are right about one thing: Proton all but advertise Luma as E2E when that is a lie. Per its usual protocol, Open Web UI will send the chat history for that particular chat to the server for each requests, where it is decoded and tokenized. If the GPU server were to be hacked, it could absolutely be logged and intercepted.

Because this is highly nuanced technical hair splitting, which is not typically a good way to sell things.

Look, we need to agree to disagree here, because you are not changing your mind, but I don't see anything compelling here that's introduced a sliver of doubt for me. If anything, forcing me to look into it in detail makes me feel more OK with using it.

Whatever. Have a nice day.

SMH

No one is saying it's encrypted when processed, because that's not a thing that exists.

Yes. They support IMAP. Which means, IMAP client can read your mails from the server. IMAP protocol does not support encryption, so any mail that does not add another layer of encryption (like GPG with encryption) implies that your mail is available in plaintext through IMAP, and as such, on the server.

If that's not enough, when you send a mail to a third party that just use plain, old regular mail, it is sent from their (proton's) SMTP server, in plaintext. Again, unless you add a layer of encryption (assuming the recipient understands it, too), it's plaintext. On the servers.

Receiving is the same; if someone sends a mail to your proton address, is shows up in full plaintext on their SMTP server. Whatever they do after that (and we've established it's not client-controlled encryption), they have access to it.

In the case of GPG with encryption (not only for signature), then the message is encrypted everywhere (assuming your "sent" folder is configured properly). But that requires both you and the other party to support that, which have nothing to do with proton; you could as well do that over gmail.

So, no, not a bold claim. The very basic of how emails standards works requires it.

Now, I'm not saying that Proton have nefarious plans or anything. It is very possible that they act in good faith when they say they "don't snoop", and maybe they even have some proper monitoring so that admin have a somewhat hard time to check in the data without leaving a trace, but it's 100% in clear up there as long as you're not adding your own layer of encryption on top of it, and as such, you, as the user, have to be aware of that. It might be fully encrypted at rest to prevent a third party from fetching a drive and getting data, logs might be excessively scrubbed to remove all trace of from/to addresses (something very common in logs, for maintenance purpose), they might have built-in encryption in their own clients that implement gpg or anything between their users, and they might even do it properly with full client-side controlled keypairs, but the mail content? Have to be available, or the service could not operate.
