Recent tech companies notoriously have voting rights concentrated among founder-executives; that is very much against the norm for the majority of public companies, where CEOs can actually be fired / replaced by the board.

Zuck/Brin/Page's argument was that their tech visionary abilities deserved special protection to take risks others don't see. You're seeing a lot of investors dispute that increasingly. And that argument has no traction at all in more mature industries where senior management is more of an actual management role, serving as employees of the board.
