I can certainly see that Hexbear and the other two are very vocal and toxic here. Engaging in some discussion or getting my views challenged is fine, I’d rather not close myself in a bubble, but it’s sad that they would be so quick to insult and ban you. It does worry that they have some of the biggest communities. I wish I could say “oh well the protocol is neutral” but I think that with most OSS projects it matters tremendously who is at the helm; also, another poster outlined quite well that these instances seem to be the showcase for the system.
