I used to work for a fintech. As new employee I had coffee with a colleague who explained KYC, AML, and other compliance topics to me. They mentioned that marijuana businesses can't bank their money due to these considerations as it would make banks knowing accomplices to the federal crime of trafficking a controlled substance. This threat is material because cannabis, unlike adult content, is actually illegal, so I don't think it's a substantially similar example to what's mentioned in this thread.

I understand that cannabis is slightly different, but my other examples aren't.
