I agree completely that the big porn sites are a massive part of the problem, both for their lack of interest in checking that the content they host is legal in terms of performer consent/wellbeing, and their lack of interest in protecting copyright and paying creators (one of the biggest problems the ethical/fairtrade producers and performers face is having their work pirated by the big tube sites.)
One of the major problems with the big tech companies as a whole is their lack of interest in things like copyright TBH. It ties in with the 'disruption' trend, which is basically the insertion of middle-men into the client/provider relationship, which benefits neither (though that is another topic, to an extent.)
But porn-bashing, as always, benefits no one and is a distraction from economic injustice and the erosion of rights - everybody has to accept more surveillance and the concentration of power in fewer hands in order to Stop Porn...
