Exactly my thoughts. Elon is not liked by the government for some reason. He has Tweeted about the idiotic level of government spending, pointing out it is not sustainable. But there has to be more to it than that.
Elizabeth Warren is fighting with Elon.
IMHO it was stupid of him to respond to her barb, but it was equally stupid of her to have made the criticism in the first place.
With any luck at all the elections will fix the issue by trimming her wings quite a bit.
