By all means, fuck Meta to the moon and back, but for goodness' sake, users on federated servers can choose to block the domain with the same result, not to mention that admins can simply restrict it (see social.coop/). It just isn't so black and white as people are making it seem.
Federation with a bigger platform is realistically the only way for Fedi to become mainstream, and at the moment Meta seems at least to be trying to be communicative. And with their quite unvaluable userbase they really don't have enough leverage against the privacy-concious Fediverse to turn AP into MetaPub. For now.
