@juergen_hubert Meta has no incentive to remove the lock-in of their paying clients beyond what might be stipulated by law.
The reasons for them "embracing" the fediverse are thus likely a complex long game.
Still, my feeling is that the fediverse will win not as a social media platform but because it is a fundamentally different proposition, it is a web 3.0 of sorts.
Hopefully this "attention" will be used in a positive way, to get to the next level.
