If he doesn't think there is value for money, it is appropriate that he moves. He doesn't have a moral responsibility to prop up California if he doesn't think they are spending his money effectively.

It's overrun with Californians
He is being attacked now because he is making powerful people uncomfortable.
Then there were the overt stock manipulation games he played. He could get away with them because he is stinking rich. Most other people who tried that would have been charged.
How many years has he been promising fully autonomous driving just as soon as they finish polishing the software?
Then there was the boring company. The flamethrowers. The flopped solar roofs project. The cyber truck. The 18 wheelers that were due years ago. The string of dalliances with young girls. The names he gave his children. His juvenile meme/twitter practices.
There were many of people who didn't like Musk long before he mentioned buying twitter.
Most entrepreneurs run experiments that are unsuccessful and end up pulling the plug.
Musk was praised when he was doing cool shit (neat cars and rockets). Now, he's wrecking something people like, and looking like a complete tit while while doing so. Somehow he's shocked that praise doesn't follow.
Twitter was pure ego, he's never going to profit from it, financially or popularity.
