One piece of context that's important is Pornhub only submitted to those changes due to mass public demands for credit card processors to cut them off, largely due to reporting on this exact problem by Nicholas Kristoff[1] in the opinion section of the New York Times.
Idiot that I am, just clicked a Pornhub link on my work computer because it was "non-porn"... I guess today I learned Pornhub is not blocked on my work computer.
This has been the case for over a year https://cdn.arstechnica.net/wp-content/uploads/2021/02/Pornh...
Also FWIW they also allow non-porn content. For example https://www.pornhub.com/view_video.php?viewkey=ph604a53bb0c9... And as you can see, it gets a plenty of views.
