For me, the reason why Delta Chat hadn't caught up on me is stickers. There's a sticker picker on desktop, but not on mobile, and its behind more settings. Weird that it doesnt do it like WhatsApp where stickers are added to personal collections (favorites) that only sync between accounts and can be added manually; it's not necessary to make it like Telegram or Signal where you can add a collection from a repository.

For chatting it is really enough. Like email.

There is not much they can do about it short of shutting down the entire server. Due to how matrix functions internally any sufficiently large federated homeserver replicates most of the entire network.

There is: XMPP

yeah I did the ansible. You just fill out a config file point it at any Linux server with python installed and it’ll set things up for you

Good idea. That makes me wonder if voice over IRC is a thing. I feel like there might only be four people who know how to use it, but I bet I would enjoy hanging out with those four people.
