Google, Facebook, et al have dual class/super-voting shares. The top people have more than 51% of the vote.

Tesla is an outlier here -- Musk currently has 20%, and that's up from like 12%.

Jensen has like 5%. Jobs owned 11% of Apple when he was forced out.

It should be fairly obvious why people who control the vote of q company can get away with more than people who don't.
