The problem with that argument is that there's value in something being not Facebook/Meta (or Twitter, or another corporate owned and run mega service), but that value isn't as easy to demonstrate as "here's a bunch of shiny features", and once people are locked in, the focus shifts from improving the service to monetizing the service, making it rapidly worse for everyone.

People largely don't think about how the services they use are structured, until any inherent structural issues come back to bite them. Twitter's an obvious example, with people who were dependent on it for their livelihood from a networking/advertisement perspective ending up in trouble when the service went south. Reddit's another example, although how that ends up is still TBD.
