For me it was when he slapped a "when it's done" on Osana. To be fair I never financially supported him or anything, I would check his channel and blog once every few weeks, which is why I didn't hear of the drama until just now. However I am old enough to remember the "when it's done" label slapped on Duke Nukem Forever and the first S.T.A.L.K.E.R. game. In both cases it was used as a cheap retort by the devs to get nosy fans off their backs, and an admission that the games were stuck in development purgatory. Both games eventually got released, but only after some serious intervention. The original developers would not have been able to finish it out of their own accord.

The whole drama around him as a person, eh. He pitched the game on /v/ for crying out loud, I would have been more surprised if there had been no skeletons in his closet in that regard. The coding skills I can't have an opinion about, since I don't know the first thing about coding. I do know a lot about business administration though, and from that perspective he really dropped the ball in his latest videos. As said, he pitched the game on 4chan, so he can't really tell us that toxicity by fans somehow got to him. He should have just ignored the rumors, hunkered down and completed an Osana/demo build within a time frame he announced early. Attention towards his game has been bleeding for over a year now in lieu of any tangible progress, and a fixed date at which Osana would be released for better or worse would be the only thing keeping the non-diehard fans interested. But he chose to cut off those followers, so here I am.
