That wouldn’t necessarily be a good thing.
Someone wrote a good article about how Google bullied their way to kill XMPP. Something to keep in mind with what Meta is planning.
Yeah it's support a platform, make that platform dependent on you, then abandon the platform. The users who remain are left with the option of abandoning the platform as well, or sit in a graveyard.
That article was a really interesting read! In my opinion, while integration can be a good thing for many aspects of the world, we can't expect the giant company to not try to swallow us whole, which is why we must stand up to monopolies.
