Pornhub is just good about making news about them, raises their profile and perception as the main porn site.

It’s not just pornhub. There are already a handful of others closing off service as well.

Also, porn sites can just white label their UX/content kinda like how there’s a million pirate Bay proxies

I was setting up an 8mm projector to watch porn in 70s when I was still middle school aged. (Adults on screen)

they’ll pick up all sorts of malware on their devices

How so? Unless they are downloading sketchy things, there is no reason for them to get a virus with a reasonably up-to-date browser.
