For anyone who lacks the advanced level of age I mean experience some of us have, you should read this Wikipedia page on Embrace, Extend, and Extinguish
I guarantee this is the goal of Meta joining the fediverse
https://en.wikipedia.org/wiki/Embrace,_extend,_and_extinguish
"If Meta’s P92 project became as popular as its other online services, with hundreds of millions of users, it could also swamp the rest of the fediverse. In that case, Meta would be able to diverge from the open standards, for example by blocking the ability of users to migrate to other instances, in a classic case of embrace, extend, and extinguish."
