I don't think it is fair to say that he's trying to sabotage EVs in general. If he did want that, he'd probably not open up the supercharger network for other EVs.

Thats a lot of work and opposition to face only to run a company to the ground. I think he was always an ass who sided whichever way for money. He really pushed ideas of being climate conscious, EVs with Tesla, appealing to those that were willing to support, purchase, invest, etc. Now that Tesla is successful I feel like he gave up "pandering" to that group of supporters he never truly aligned with and now he can be himself... Unfortunately.
