Too bad there aren’t other porn sites with massive libraries of content that apparently no one in power has noticed.

The states aren’t banning PornHub from being accessed there, PornHub are blocking themselves from being accessed from those states so as to not need to comply with new state laws requiring ID proof of age to access because they don’t want to handle personally identifying information of end users. So basically you’re just waiting for law enforcement to notice and charge them, and then find out if they’re run out of somewhere the state can reasonably do anything about it.
