About 78% or so of the shareholders voted in favour of the deal. And will probably vote again when asked.
The lawsuit was done by a shareholder with a total of 9 (nine) shares.
If those 78% of shareholders believe that Elon having $56B MORE is a priority in their lives, then should just voluntarily give Elon their shares or send him cash.
Companies and shareholders meetings work a bit differently than what you suggest.
Other than that, the grand majority of Tesla shareholders are quite happy with the financial state of the company and would like for Musk to continue leading the company and be compensated for it.
It turned out this guy's claim was justified, given the court agreed. Again, if it was really important to these investors that Elon have more billions, they do not need any courts permission to just send him money.
Try to think about this from the shareholders’ point of view.
They want Elon compensated with the bonus he hit very difficult growth targets to earn because they want to make money from him further growing the company.
If they just donate the shares they personally bought, then they don’t make money. They lose it.
