It's hard to agree on this one.
Personal anecdote: In 2010's I worked in a micropayments broker linked with all telecom companies.
The whole thing was: that NSFW creators used a shared SMS shared code (i.e. a SMS number that receives messages for several creators and the code (for instance HNCODE25) was used to move money to a balance account) and for each of the payments that people used to do with them the telecom company got 15% slice, and the rest the telecom moved the money to the broker.
Another point: In Brazil due to the PIX [1] almost all of those payment platforms (Paypal included) are becoming irrelevant because you can generate random tokens that can be hard to trace, and all the payments occur instantaneously giving enough time for withdrawn before any attempt of censorship and or any policy change.

About the article itself, it's surprising to me (and I assume some sort of intentional ignorance here) that even in the current state of technology we do not have a "dumb pipe" payment system as before and we're still relying upon those middle man actors or not-so ergonomic alternatives as P2P crypto.
