If Musk is actually using Tesla devs at Twitter he better have a rock solid contract for service between the two companies. Otherwise he opens himself up to a shareholder lawsuit for misuse of Tesla corporate resources.
U wot. If Tesla engineers do work for free for a company owned by one of the shareholders, there's clear damage there in the form of misallocation of resources.
Uh huh. Let’s say Musk writes himself a check from Tesla for an extra $100,000. He cashes it, but the next day TSLA is up. No problems there? No legal risk?
Now let’s say that instead of a check, he gifts himself $100,000 of Tesla engineering time.
