But is he wrong?
Probably. I know there were rumblings of lawsuits from shareholders about the boards fiduciary responsibility in [attempting to] block the acquisition, but I think an argument could easily be made that the board figured that Elon was a polarizing enough figure that overall the acquisition would cost Twitter value and money, so they were acting responsibly. At least I assume that's what the board's lawyers would say.
So it's probably a frivolous threat.
On top of that the State of Florida's pension fund's stake in Twitter is pretty small, and the pension fund is well leveraged against market volatility, so there's some question if it would actually hurt FL. But the real issue is that DeSantis is a government executive that has much more important *expletive deleted*it to be working on in FL. He could work on the Open Carry he talked about, for instance. Ron has really embraced the Trump "Every headline is a good headline" idea, and, I think, really enjoys seeing himself on TV. So he says *expletive deleted*it that will get him on TV.
