I second the controversy, owners of the program kinda suck (like Lemmy really) but mainly I was using a fork of Conduit for my server called Conduwuit but the single maintainer got bullied off the internet and they couldn’t hack the abuse, so they had to retreat and stop maintaining everything to recover their health. Here is their statement. They were open about having a furry/puppy kink and so constantly got people attacking them, spreading rumours and accusing them of bestiality and paedophilia.

Anyway, as my favourite fork was no longer maintained, and I heard that Matrix was only as strong as its proprietary protocol, I chose another.
