Okay, so no, it’s not hacking. It doesn’t fall under hacking laws. It’s not illegal to sell hacking tools. Basically, everything you said is wrong.
In this case, it’s all about copyright and the DMCA, which made it illegal to break the copyright protection systems companies put in place or to make or distribute tools to break copyright protection systems.
So, nothing to do will selling things or hacking. Everything to do with copyright and draconian dot come era laws.
