Not really, there's an OR logical element present in our world.
Divide et impera, applied to engineering. For 80% of things this fast cool solution works, for 20% the simpler one works. The aggregating element to make using both in their own situations transparent reduces reliability just a bit, but the efficiency gain is visible.
And the "80%" and "20%" solutions can further on too use such unifying elements to aggregate different solutions for them. To improve efficiency without additional failure points (except for aggregators).
Nobody does that because the "80% solution" producer wants to capture you, they don't want alternatives, they want power, and it's a honeypot.
It's up to you the customer to understand this. In the classical model. Also see customer associations, which are like unions inverted. Isn't it funny how we have big businesses organizing, but not labor and not customers? While for them it's much more important.
As you can see, the aggregator is very important here. We need standards, so that all social media would compete with other social media in one interoperable world with standardized interfaces, all search engines would compete with other search engines in one interoperable world with standardized interfaces, all file hostings ... you get the idea.
