Yeah, but Kotick was not really the real issue. He's a straw man of sorts, a target dummy, designed to draw fire for unpopular decisions.
It is the board and shareholders who massively incentivized him into that behaviour. CEOs are brought in to act in the interests of shareholders, while also abstracting them away from blame and direct culpability.
The goal of blizzard (and any other publically listed company) is wealth creation for shareholders via share price growth, not making games per se.
