Yes: Pornhub had a massive problem, not with child depictions, but with "revenge porn" and similar materials. They definitely needed a slap on the wrist for that one.
But... this is not about children, not about "revenge porn". This is part of an organized, fundamentalist-Evangelical-Christian anti-sex-work campaign that goes back many years (https://theconversation.com/evangelical-women-are-shaping-pu...), whose biggest successes to date were FOSTA/SESTA, and (in countries where prostitution is legal) who uses the current Coronavirus crisis to further calls for banning brothels and other sex work indefinitely.
Make no mistake: the ones suffering at the moment are not the people behind Pornhub/Mindgeek. The ones suffering are the countless content creators that already had their lives screwed when Coronavirus restrictions made face-to-face sex work impossible, and now the biggest platform got hit with a payment cutoff. And this is intentional.
