I think the difficulty with GamerGate, and in this case with Pr0gramm, is that "users" or "members" is not a singular entity. The GG-people that donated to charity are not the same people that threatened women. Same goes for these Pr0gramm users i assume.
Maybe--until it became fully and completely obvious that GamerGate was just grievance against "the SJWs", there were certainly some people who actually bought that it was about some kind of ethics. (That has obviously since changed to the point where "ethics in games journalism" means you're probably fitted out for some Hugo Boss.) But--and why I pointed it out--is that those donations are then used by the shitheads to shield their behavior and legitimate themselves, and clearing that tactic in the open is useful and important.
