I don't personally care one whit about the fortunes of Pornhub but this sets a very bad precedent for the internet. The payment processing duopoly is a huge problem, they are able to dictate way too much of what is allowed to exist on the internet. Today it's illegal pornography that everybody agrees is terrible, but that's how it always starts. The safe targets, the stuff nobody objects to, to establish precedent. Once they have this power to censor it is extremely hard to walk it back.
