Elon needs to stay there to help protect things like federal tax credits for purchasing an EV, clean fuels, solar power, etc. I don't see the issue frankly. You can believe the Koch Brothers have their anti-renewables people speaking to him every chance they get.
He is not backing up what the guy says or does, generally speaking. I hope he is "the voice of reason," if/when he gets asked. Let's hope he gets asked frequently.
