Selling someone's program and not giving his shares has nothing to do with copyright disputes.
Selling unathorised copyrighted material is not about having a different point of view.
Selling a stolen compiler is not about giving better support, than the copyright holders.
The analogy with anyone having pirated material at home is very skewed unless the person in question is selling his pirated stuff few thousand units a year and in the $100+ price range per unit...
I feel sorry in advance for any developer dealing with them. Hopefully people have been listening over the years - if not, this is going to be an "interesting" ride for them.
