Call it "providing financial services to a neglected/stigmatized sector of the entertainment industry and bringing the benefits of official banking and regulations", then. Yes my first comment was probably worded with an inflammatory bent, but this does genuinely seem like an underserved sector.
Akin to the problems legal marijuana grows and dispensaries have with accessing banking services (though in that case due to federal regs), the stances of the entrenched industry leaders seem to bring more negatives than would come from providing the needed services.
