NCOSE convinced mastercard and visa to cut ties with porn not for the sake of advertisers, but because they convinced them that they could be potentially liable for facilitating illegal activity- the exchange of CSAM, prostitution and human trafficking- happening on the porn sites they were partnered with, which in NCOSE's opinion is all porn sites, and all porn period, since they believe all porn is human trafficking.
Blaming the sanitization of the internet solely on the vague specter of "advertisers" ignores the real, nameable groups and their extremely straightforward christofacist goals. It promotes apathy, pointing at an ambiguous target that feels as impossible to combat as the machine of capitalism itself. When it's literally just these specific guys, and like two or three similar, equally identifiable organizations!
I'm not saying sites like facebook don't have a vested interest in looking squeaky clean and family friendly, but tumblr, pornhub, onlyfans, patreon and gumroad did not move to ban porn because of advertising. Tumblr has never attracted the kind of advertisers who care, and pornhub, onlyfans, patreon and gumroad don't make the bulk of their money from ads, but from user transactions, which MUST be facilitated by an electronic banking platform in order to be safe and reliable.
Tumblr's porn ban was due to FOSTA/SESTA meaning the could not continue operating unless they either dumped nsfw content or went adults only and implemented costly and draconian age verification protocols that, frankly, no one was going to put up with for a mediocre blogging platform. The others folded under pressure from the electronic banking platforms, which threatened to drop them as partners due to the pressure *they* were under from NCOSE weaponizing public opinion to create a flurry of anger and condemnation towards these companies "facilitating human trafficking."
The enemy is not hiding, we know their names! They come not in the name of capitalism (who merely rides their coattails when convenient) but in the name of puritanical Christian Fascism.
So no, it's not the puriteens. It's their parents and grandparents, on an open crusade to enforce Christian anti-sex beliefs on as much of the world as they can manage.
