It's only ineffective because it hasn't been tried at scale. If you can co-ordinate enough voters to move an election, you can co-ordinate enough money to influence corporate governance. A lot of AGMs are simply rubber-stamping exercises (look at how many directors are voted in again and again with 80-95% of the vote?!) It does not have to be this way. You don't have to literally own Amazon to change their ways - in theory you can buy one share and ask some pointed questions at the AGM. If the other shareholders see that change is in their best interest, they will vote accordingly. Sadly, most are asleep at the wheel.
