People have been forgetting that home routers come with something called parental controls.

When my wife and I first signed up with Virgin as our ISP there was parental control turned on by default. Had to put in my credit card info to be able to flap.(Edit: Goddamn Autoassume! FAP not FLAP) This was 2021ish? So before the current stupidity.

Also, it's easy to feel like this is all being pushed by parents who just straight up refuse to properly parent their children...but it's mostly being championed by Puritan lobby/pressure groups. They think even totally consensual, CIS/HET amateur porn is disgusting and sinful. They don't want to see, so they're on a mission to make it so literally no one can see it.
With help from companies and people who have a vested interest in creating a panopticon-esque surveillance state. And the rest of the people involved in passing it are too old or ignorant or paid too well by the other two groups to stand in the way of it, or to have cut out the really egregious shit from these bills before they were passed.
