Why not towards the payment processors? Just because they gave in to a loud activist group instead of just ignoring them like they ignore the rest of stuff processed with their services?
Why did they react to them and not to other? Seems like the companies are atleast somewhat "in agreement" what the activists demanded and thus enforce the policies.
Because lets be real, even if the activists reach a bit more publicity, I doubt anyone would really force the processors to do something about it, since everyone depends on their services, so most would simply ignore it.
