Are you suggesting messaging doesn't have dominant players or that Google didn't integrate with XMPP and then eventually break compatibility and some folks argue set back XMPP in mindshare and marketshare.
XMPP is essentially an open standard where you can host your own relays. The concept was to fight against iMessage and Google Chat and Blackberry, etc. It was just as popular as lemmy/Kbin is now. Hell, Mastodon dwarfs Lemmy as a whole and isn't under attack.
There's just no real evidence this is a concerted effort to ruin the fediverse for corporate gain. It's much cheaper and more profitable to exploit it. It just isn't worth it right now. Meta sees an opportunity but mainly because it wanted to try and exploit Xwitter's current state. That's why it's not even on the fediverse yet. It's not that concerned.
Occam's Razor.
Edit: added clarification (emphasis added to highlight the change).
