People are predatory, and will use your licence to their full benefit. I feel like a jerk saying this, but this example is exactly why I licence my intellectual property under GPLv3 as much as possible. I retain rights, and others are forced to play by my rules lest they enjoy litigation. But more importantly, if my work is stolen, I have legal recourse because they aren't releasing the source to their derivative work.
