My evidence is that in America people sue for these things left and right all the time. It's a popular pastime for lawyers to get a class action lawsuit for securities fraud together. But as far as I can tell, Musk / Tesla weren't convicted of these things in conjunction with the sale of Tesla stock to buy Twitter.
There is a meme for this kind of move. It's pump and dump because it isn't worth what the underlying assets are worth and because there is a sale. Whether people sue for it and whether or not they were convicted is immaterial.
