Did he/didn't he steal? Dunno, though there's a fair few bits of evidence in the various lawsuits (Winklevoss, Greenspan)
But if you didn't know about any of that you could make some inferences. Like his neverending "ooh, shiny new thing, want" (and then lie to people along the way, trick Indians into signing up for your internet.org thing)
I was willing to take his side on a few things because the political situation is genuinely unclear and the public has been misled but then right after he wrote the open letter to Jim Jordan about censorship coercion (which was a real problem, I want to see more tech companies talking about it) he does this https://news.ycombinator.com/item?id=42651178
It's kind of like he has raw bits of intelligence but doesn't quite know how to piece it together and besides "his" inventions (even FB) are put together (largely?!) by other people
