I really, really don't buy this explanation. It's a convenient scapegoat but I strongly believe it doesn't apply here. They came down on Patreon for this, but we never heard anything about chargebacks. Furthermore, why are they telling companies specifically what they need to block? If they are able to be this specific about why they want to block certain content, then why in the world can't we also hear the empirical reason they bothered to light the fire?

I also don't think that accusing MasterCard/Visa of 'funding terrorism' is a good rebuttal to this. Terrorists are probably better at evading the payment networks than legitimate content creators that want nothing more than to legitimately accept payments.
