There are comments on other articles (like https://arstechnica.com/tech-policy/2020/12/pornhub-purges-all-unverified-user-uploads-in-wake-of-abuse-allegations/?comments=1 https://arstechnica.com/tech-policy/2020/12/pornhub-purges-a...) where people are quoting statistics that suggest that PornHub has very little problematic content compared to other sites, such as Facebook. So the question is - why don't Visa and Mastercard take issue with those other platforms? Are they going after Pornhub simply because it sounds "bad"? Is it because they are caving to pressure from religious groups or feminist groups or some other organization? Or is it because other offenders may espouse political views that Visa/Mastercard are aligned to? Or is it that Pornhub is smaller and they can afford to lose them? Either way, I am not a fan of duopolists picking winners and losers, instead of the law picking them.
