Short term, yes.
Long term, no. Asset flip "Hentai hitler" tier sludge is not a threat to them. This isn't a moral crusade either, because they allow Only Fans, and other questionable entities to process payments.
As for the specific reason, I don't know. Choose any conspirasy theory you like, they're all good. Is it because of the Epstein stuff in the news? The timing is right. Is it another attempt to shut down popular indies like Palworld and Schedule 1 after lawfare failed? Sounds probable to me.
