Things like this are why I have become disillusioned with Open Source, and why latest projects have been closed source. The GPL is a good enough idea but it is basically impossible for anyone to realistically enforce. If a corporation is selling an optimized binary, then it can be almost impossible to prove that there was any violation of the GPL without viewing the source.
> The GPL is a good enough idea but it is basically impossible for anyone to realistically enforce. Really? If you find a piece of proprietary software does basically the same thing as yours, and the binaries contains the same strings/artwork, then it's reasonable to make a legal case of it. You can even contact FSF and they'll take it further.
A lot of open source stuff is libraries and utilities though that is pretty entrenched in the code. It is hard to even find out about a violation, let alone prove anything.
Imagine I came up with a new algorithm to do Fourier Transforms 10% faster than FFTW (or whatever the current market leader is) and make a library and I release it as GPL. A company could fairly easily just import it to whatever project they’re doing, and it would be extremely difficult for me to prove anything, especially if I don’t have any obvious things like strings in there.
That’s not even taking into account that it would be relatively easy for a corporation to just pay a junior engineer to do a direct “port” of the library to another language and pretending it’s their own independent work.
