I don't think it was a good idea for instance admins to agree to talk to Meta under a nondisclosure agreement, but that DOESN'T make it an excuse for people to go and harass those admins. If anything they're the victims of Meta IMO, and a lot of them may still be in favor of blocking Meta regardless of whether they agreed to the meeting or not. I think we have to stick together in situations like this and act accordingly, keep in mind that "divide and conquer" is a proven strategy.
