The drm people just don't realize: Programs are data. F34A8D... or 10101000111101010010...
Data is, almost by definition, easy to copy. And the problem with encryption, or locking, is that sooner or later the key's got to be sitting, right there, on the user's computer. So a pirate can simply get the key, decrypt or unlock your program, and upload it on bittorrent.

And I could argue that the pirate isn't really doing anything bad. He is giving people stuff. You could argue that J. Random Pirate is a Robin-Hood like character, Stealing from rich people, no, corporations, imaginary, impossibly rich people, and giving to middle-class, real people. And as far as I can tell, no singers or actors or even managers have been harmed in any way by such stealing, although, can I call it stealing if no physical object is gone?

Sorry, my train of thought was derailed. Anyway, no, you can't use a GPL C library in a closed-source program, unless you find a loophole.
