So he was on a leave of absense, and now is no longer on such a leave? This is only an attempted coup if you think the leave of absense was a pretense, but they give no evidence of that in the article. I saw it suggested that he usually has wild ideas after returning from burning man, and the board wanted to insulate the company from the effects of that. That he's now back is evidence for a theory along those lines, and contradicts a theory that the board was trying to get rid of him. But I have no insight beyond that.
