It's not insane, and it's not a new idea. That's always been a right you have as a shareholder in a public company.

And you don't vote by selling your stock, you vote via proxy ballots. Which too many individual investors don't do.

Yes, you get a vote which is a simple yes/no on whatever is brought to a vote - but you don't get to say what is voted on.

Second this motion. These shareholders are not family holding shares in a family business. If they’re not voting by selling their stock then can we really say they’re fed up?
