I am familiar with the philosophy of the GNU program. I reject it as idealistic, not mention wrong on several points. You can argue the Open Source software is more secure or that you feel more comfortable running it on your machine because you know what its doing. But you cannot say that someone is doing something unethical or immoral by licensing closed source software.

I would say I use 90 percent open source software, or free in the gnu sense, but not for moralistic reasons I just like it.
