All this talk about licencing is starting to hurt my brain.
Just how effective is this open source copyright?
For example if I take some GPL (or some other licence that do not allow
commercial distribution) and based on that code develop some commercial
program that I sell. Who will know, and how, that I used GPL source
if I do show source code of derived program to anybody?

On the same note: If some big (or small for that matter) company take
GPL game engine and release the commercial game how is anybody able to
prove that it is using that particular game engine?
