I would be much more supportive of a "Block Fediverse participants that do / don't do X" proposal than a "Block Meta" proposal.
E.g. Do: respect posters' indexing/not wishes. Don't: attach adverts to posts. etc.
Then it becomes clear what Meta has to do to participate, and what everybody else has to do, and that can change over time.
@J12t sadly, that's like saying google, don't be evil... Yep:(
