I heard a story a while ago about how marajuana-related companies in colorado formed some financial institution in order to deal with being blocked out of the wider financial ecosystem.

The piece of the puzzle I don't understand yet is why credit card processors appear to have taken it upon themselves to be the moral police. They could very easily make the argument that the use of money transferred isn't their problem. That seems to have worked for the NRA. Why did they get into the business of kinda-sorta-but-not-really representing the police?
