Don't quit that easily! I remember reading about the minecraft dev here on HN ~10 years ago when paypal froze his account with 20M. It was the first time I heard about the game so I checked it out and thought it was complete crap and probably a scam if he really had 20 million from selling this junk of a game )))
He ended up bowing out from the game and largely retreating from the tech space entirely. Lotta reasons for that; but mainly -- as a wildly successful entrepreneur he suddenly found himself to be a highly influential figure whose every casual statement caused news article to get written[0] and he DID NOT WANT THAT AT ALL.
True, he made a ridiculous amount of money, but I don't know if it was worth giving up his creativity.
If the casual statements were "I like cheese" or "tabs are better than spaces" that would not have been newsworthy. "Feminism is a disease" and "Q is legit" are rather more controversial statements.
I don't want to apologize for those statements -- its clear that they were wrong. However, I do think that originally they were genuinely a result of a mental breakdown.
As for the "Q is legit" statement, he quit Minecraft before Q was a twinkle in 4chan's eye. I don't follow Notch and haven't for years. I'm not surprised a lonely tech enthusiast was ensnared by the Q cult, though.
