Sure. Let them whatabout. But to us, consumers, it shouldn't matter.
We know the stores aren't responsible, so we shouldn't attack them.
The processors are. For Visa and MasterCard it's pretty obvious. Itch, as you said, puts direct blame on Stripe, and I think we can trust that.
As much as processors need banks, banks also need processors. It's a sort of symbiosis. Damage to one actually trickles onto the other. So pressing onto processors isn't a mistake. It'd be foolish at best and malicious at worst to suggest that.
Now that we have leverage as users and consumers, having started a push which made way and caused a response (first the prepared phone statement and now a press release), the absolute wrong thing to do is bacl down and say "sorry, we were wrong, it was B after all and not you, A".
And look at it this way: There's less payment processors and they're smaller than banks. If you suddenly turn to banks, you won't accomplish anything because to them, a few consumers who aren't their customers doesn't cause them even an itch. But if payment processors come to them it might.
With SKG going as well as it is, wouldn't an ECI on chat control be in order?
