I appreciate your engaging with me on this, though you haven't convinced me yet :)
I'm in agreement with you that Meta absolutely intends to exploit "the fediverse" for their own benefit: to gain users by making their platform valuable.
But... my take on this is: so what? If the fediverse can only operate when all actors are benevolent and selfless, then it won't last very long at all. And, even if it does, it's not as valuable to me that way, so I'll be leaving. What's the value of a fediverse if it doesn't even federate with any of the major players that have the most resources?
This would be even worse if we defederate later, once it turns out that Meta is trying to do something that really warants a defederation.
I honestly don't think that anything ever justifies defederation, aside from technical limitations. If you want to run a gated forum, fine, but then don't call it a "fediverse". It's just a forum. Would we say that it's fair for Google to say "From now on, Gmail will not send emails to @republican_party.org email addresses because we don't agree with them"?
EDIT 1: I haven't made my point very clearly. Am currently editing this message to make it clearer.
EDIT 2: Left the comment the way it was. Am struggling to express myself properly-- this is the best I can do at the moment.
