As the agreement was illegal - a judge has ruled it was - so Tesla the company should not honor it.
Musk took Tesla public but doesn't seem to want to abide by the rules, he seems to be treating it as a private company owned by him.
In particular it seems like the Tesla board does nothing to stop Musk pillaging the company, e.g. this promised bonus many times greater than all of Tesla's profits to date. Tesla and Tesla shareholders are going to have to pay for that.
Even when he assigns Tesla engineers to work for another one of his companies, and allegedly transferring talent away from Tesla FSB, a real pain point with litigation beginning in earnest - this feels like straight up stealing from the Tesla company & shareholders?
In summary Musk just doesn't want to play by the rules that made him a billionaire, nothing new here then.
Lots of lots of questions here, most of which mean I don't think they should be comfortable with paying out many times Tesla's total profits to date.
