Fairly often, especially for founding CEOs since so much of the company tends to be tied to the founders. And generally when a founder CEO is ousted there's two reasons: 1) there's an incredible amount of bad press (think of Uber and Travis or Papa John's John Schnatter) or 2) the board/investors think that they need to replace the founder with an experienced CEO (think Google). Here, only the first applies.
