I don’t have any problem with the pornography aspect. I consume the product, I have many friends who make it (and do other sex work), I publicly advocate for decriminalization of prostitution.
The thing that’s sleazy about it is that none of the piracy sites are pirating one brand. So if the owner of one brand is operating such a site, he is certainly peddling pirated work from competitors, which is probably diverting revenue to other sex workers and even the ones who perform on his payroll.
It’s pretty likely he’s doing other shady shit besides.
For what it’s worth, this is an opportunity for any disgusting person because the law and the stigma around sex work make protecting workers difficult. A certain brothel owner in Nevada who died recently was a known creep but nearly ran a successful bid for congress because few people care about his victims.
