A lot of rules have been broken in Musk's relationship with shareholders, but this one is truly interesting. He has shown that he can have some impact in robotics/AI (if you see the Tesla robotics work and Grok via X to be some indication) and wants to be heavily compensated for developing that tech within the Tesla umbrella (and thereby delivering additional value to Tesla shareholders). I personally think it isn't worth the insane price tag as if he does become successful in those fields in say some separate company, he would still bring that value to Tesla in the form of favorable contracts etc. It just wouldn't be as big a smash homerun to have it all in-house. Regardless, Elon gets paid (through Tesla value going up or the other company making a profit) and shareholders see SOME growth just not all of it.
