I don't think they meant brand risk to Stripe. Credit card companies don't like "immoral" businesses and refuse to do business with them.

There are quite a few stories about porn stars having their credit cards closed just because of how they make a living.

There is a portion in there that mentions Stripe sees this regulation as "overly moralistic" and that credit card companies have "old school morals".

Correct; the brand risk being referred to is card network brand risk. (Which they're very sensitive to.)
