The claim isn't "we don't like it", the claim is "this is damaging to society".
I don't agree with such things in many cases (and many people disagree with me when I'm the one saying something is damaging to society), but it's important to note the difference or you will always be arguing against something other than their claim.

It's kinda the job of the government to decide such things; but an automatic extension of that is, it's not the job of the payment processors… and I think they should be banned from doing so because it's damaging to society to let them take on this role.
