Right. The question is, if I made a program, and for some reason they wanted to extract a fee or make me delete it or something, would a court take their side?

Right. The question is, if I made a program, and for some reason they wanted to extract a fee or make me delete it or something, would a court take their side? Because otherwise what is the utility of releasing the source code of a programming library for free? Could they argue that it was only for educational purposes or something? Again, seems like a trap if it's supposed to be interpreted otherwise. In which case why should such a trap be legal.
