Okay, so, let me ask you a question: there are payment processors that process adult transactions; has a single one had its license pulled because of that? I can't find a single instance of that happening, only more instances of adult content providers being targeted this way: https://www.eff.org/deeplinks/2017/03/payment-processors-are...
I'm not aware of any instances of payment processors getting shut down, but government administrations have indeed had policies of greater scrutiny of "vice" businesses: https://en.wikipedia.org/wiki/Operation_Choke_Point
So? Spin off everything "risky" into another corporate entity, and charge more. The simple fact that they don't do this tells me they just don't want to.
This is America, nobody will ever take seriously the argument that it's not the government doing it when they can get cheap internet points by saying "but muh freedoms!1!!"
If an article asking questions about it from 2014 is the most compelling piece of evidence that this is a serious issue then I'd say it isn't particularly compelling.
Note that the "Operation Chokepoint" wasn't just about porn - it was also shutting down payday lenders and firearm dealers. The operation was stopped by the government in 2016 and bipartisan legislation passed in 2017 to stop it happening again: https://www.forbes.com/sites/norbertmichel/2018/11/05/newly-...
