Yes, he is unethical. It doesn't matter what he has done before. And we don't know why he became part of the Trump team, for the better good or for $$$.
But one thing is for sure, it's a fact: He's still part of team Trump, he hasn't denounced Trump despite that Trump and Pence stand for everything that Tesla doesn't...or at least I thought so. But even worse, Trump has done completely unethical, ****ed up things in the last 7 days...and Musk stayed quiet (except his little Twitter thingy).
I also don't think he's trying to influence Trump, that's not working anyway. He's taking the weak way, trying to make friends with the enemy for profit. I think in the end Musk will regret that he didn't stand up against this scumbag...
How does it make you feel driving a car that supports Trump?
Just my 2 cents, sorry for the swearing...
