Yes-- if he can generate much more than $50 billion in value for Tesla shareholders, and they give him $50 billion in compensation, that's a fair trade in my book.
You can claim the amount should be lower, but then your argument is with the shareholders who came up with the proposal and approved it.
So why does Musk deserve this again? Because he says so?
Meaning that Musk directed the creation of the compensation package, not that the compensation committee were merely biased. The analysis of this is on pages 103-146 of the ruling.
You can spend your time better than this ;)
The stock hit those goals, and Elon got paid.
Then one guy with 9 shares said it's not fair, and got a judge to agree.
