> As far as the Fed is concerned, any support of the illegal drug trade industry is a Felony
The Feds. The Fed is mostly concerned with managing the money supply.
And that's not exactly true, even then (the laws are a lot more specific and complex, not everything that could be described that way is prohibited at all, and some of what is prohibited under federal law that way is not a felony.) But its a reasonable approximation.
> Selling software that is targeted at helping manage, distribute, and facilitate the marijuana industry (which is illegal federally) is against the law.
That's quite possibly true, and I can easily see other businesses not taking the risk of getting involved in case it is.
OTOH, if you are going to claim that it factually is, it wouldn't hurt to cite the specific law.
