Perhaps the answer to this particular problem is for the next version go GPL to include an agreement to pay 4% of global revenue as a fine for misuse. Now that the GPL in principle (i.e. if you use it then you have agreed to its terms) has been upheld in courts it's now time to make those terms more onerous for abusive companies.
