I don't think it's so much a religious lobbying thing as it is a consent and liability thing.

If you're a processor (payment or otherwise), you have to be absolutely sure there's no CP or non-consensual content on there. The penalty for even one thing to slip through is damning, and they're under extreme pressure to be the gatekeeper on all of this.

That means you have to manually review everything. That means paying someone to sit through and review all sorts of... questionable... media. A lot of work was shipping this off to overseas review farms. And we occasionally hear reports on how degrading and traumatizing this kind of work can be.

So for Visa, Mastercard, et al I think they are more or less chomping at the bit to just be completely out of this genre of businesses.
