I may be wrong, but from what I can gather here and there, it seems that Patchwork Chimera has very interesting things to say and is now not online, for some reason. Is that right?
He left social media (not just here but also twitter, reddit, etc) because he knew a lot more than most (professionally) and didn't suffer fools, so when people attacked him for disrupting their comfortable narratives with uncomfortable facts he decided it wasn't worth the hassle.
Frankly, I would probably do the same in his position.
