HF could certainly sue but why isn't the FBI investigating the hacking?
It's not my argument so I can't say but I do think the FBI should be at least investigating if a crime happened. They might be or might already have, I don't know.
If this case isn’t covered under CFAA I think we need to rethink it. I’d be surprised if the criminal angle amounts to much under my understanding of the current laws, but I’d love to be wrong here.
