A couple of people responded to this It isn't surprising that people who want to write non-free software are disappointed that the GNU project won't help them. What is amazing is that they feel this is unfair. by expressing doubt that anyone really thinks so. I think the person who wrote this text I used to be quite pro-GNU until I tried this exercise (writing commercial crypto software for software companies) and ended up re-writing huge tracts of stuff just to remove the GNU license virus. made that feeling quite clear through his use of name-calling. He did not content himself with saying, "I had to rewrite huge tracts of stuff because its authors did not give permission to use it in a proprietary program," because that straightforward and accurate description would have shown why his resentment was unjustified.
