Personally, I don't like him because of what he always says and also posts about himself and his thought about Bitcoin and other cryptocurrencies. And what he is doing now is if he did it and also there are proves, so, he deserves it. Just let the law rules it and makes the right decision.
About Elon Musk, I never heard that SEC is now focusing also on him. I don't know the exact case, but, it may relate to how he made the short pump about certain coins.
