My community (30 members or so) of hackers switched to Matrix last October because we were expecting draconian policy which would attempt to unmask and chronicle our members identities and sentiments. We now spend more than we did with Discord but the data sovereignty is worth it. Not a plug per se, but we host our international community members content out of Germany using federated.computer.

In recent days people have been coming out of the woodwork trying to join again.
