@anildash People don’t care about who runs it, they care about social interactions being easy.
Mastodon specifically was designed to make social interactions harder; replies aren’t guaranteed to show up (especially on small servers) and there’s no quoting; aka the most basic conversation features are deeply broken.
I’m also convinced that the makers of Mastodon don’t actually use it, other than occasionally announcing something. The BlueSky devs are extremely available, and use it actively.
