>He was removed for hostile trolling of other YC founders.
Precisely, the words used by YC were "threatening and harassing" comments. To my knowledge this is the exact comment YC cited:
>All of you: fuck off. Take your morally superior, elitist, virtue signaling bullshit and shove it.
>I call it like I see it, and I helped meme a President into office, cucks.
I certainly see how this speech can be viewed as rude and disagreeable. But I don't really know how you can say that he made any serious threats or was honestly harassing anyone.
