IMHO, there's not that much difference at all whether they chase Binance or CZ since he's part of the company, owner of it when all of the acts had done. But then, I am not a lawyer, I am not the government so let it all be to them.
I asked that because, from my little understanding of business law, there's something called "the entity concept". This means that the person/people who own the company are different entities from the company.
Elon Musk might have a charge against him but none of his companies would be in court. Likewise, his company might have a court case, but it doesn't mean he's the person standing trial.
I may be wrong, but if Binance was committing fraud and the company was involved in it, then the whole company would be sued or at least the board that was involved, but if CZ alone was committing fraud, either through Binance or other means and the company was not involved then he'll be sued alone.
The company won't be going to court, but it's still bad news for the company because it taints their image.
