As I understand it, the situation is worse than that. The mere existence of GPL code poses a threat to commercial software: if a programmer happens to read some GPL code and then goes on to use similar techniques in proprietary code, the owner of the

Really? I've assumed that GPL only deals with copyright, and techniques one uses in code are matters of patents and trade secrets.
Sure, but if the code in the proprietary source ends up looking similar enough to the GPL code, it might be hard to prove that it wasn't a derived work. This is a risk you just don't want to take if your business depends on keeping your sources non-free.
This is the first time, I have heard about such a scenario and I don't think that it is realistic. For an infringement of copyright (rather than a patent), non-trivial amounts of code must be basically the same. This won't happen unless the programmer has a photographic memory or actually copies parts of the code. Consider that companies like IBM and SGI happily deal in GPLed code. Cheers, Manuel
