FSFLA: Linux kernel is "open core"

I don't, and the difference is quite significant.

Cancer is a natural, biological phenomenom. As harmful as it is, it has no will of its own. The damage is not intentional, so it's not unethical, and there's no economic drive for the cancer to spread the harm.

Depriving others of software freedom is an artificial phenomenom. Many who engage in such a harmful practice do so intentionally, so as to obtain an economic advantage, including power over others. That is unethical, and the gained advantages imply it will tend to grow and concentrate power unless it meets strong resistance that renders the unethical behavior disadvantageous.

The Free Software movement is a movement to build up that resistance. Please help us!
