If you feel hosts are a crime, then why are you using them to exploit your console? Sounds like you might have some moral issues you need to work on if this is the case. While Sony may care, there is not much they can do since the exploit itself is just an exploit, it's up to the user of said exploit to choose what they want to do with it. Also new exploits don't usually come out until the firmware has been updated to make said exploit unusable on the latest firmware thus blocking access to their online services for the most part for modded consoles.
If you choose to use the exploit for piracy then Sony if they choose to would come after you. Not the creator of the exploit since it doesn't contain any copyrighted code. The onus becomes on you, the user.
