apparently some Mastodon admins got contacted by Meta and met with them after signing an NDA. I'm quite surprised how many Masto admins want to "just wait and see, maybe it's not gonna be that bad".
I'm guessing you haven't been on the #Fediverse very long so not picked up on the ethos of most of the folk who run the various instances.
Most are very protective of what they have created as a community and are definitely not in it for the money. Some are vehemently anti-capitalist.
There are many ways to get rich. Running an instance is not one of them.
Words are cheap though. Not casting aspersions on anyone in particular, but hypocrisy is a common human characteristic. Greed has a way of bending people's principles when a real world opportunity presents itself.
