Even pointing out that people have a choice - with some work, yes, but only a little work - elicits some counter response that basically comes down to: no, you don't have a choice. I don't like that, and it also signals creative laziness.
P.S. Zoom out a little. The open web is also client/server (although peer-to-peer would be nice), that's not the point. We all need some infra, some trust, and a clear rule of law for the internet and the web to work. We just don't need big tech's view of 'social media' (there's nothing social about that) or platforms that present themselves as being an alternative as long as we have the perfect alternative - called the open web - being around for thirty years, battle tested and actively maintained by millions.
P.P.S. This is in reply to you, but read it as a general opinion, it's not a personal attack on anything you said.
