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.
If you're doing something algorithmically different and unique, presumably that would show up in the assembly.

Important to keep in mind that copyright is not patents. If they are just stealing the "idea" of your algorithmic improvement, that probably isn't even a GPL violation. (This isn't fully right as they would probably have to use a clean-room design to avoid copyright infringement. My point is more that such a situation is pretty muddy and might actually be allowed)

I don’t think it is realistic to expect a developer to load every executable that might use their software into Ghidra or something and try and find a smoking gun about how their code might be used, and then hire an attorney to put together a case on that. In the case of my example, Fourier transforms are used everywhere in a wide variety of applications, and if my implementation is only like 10% faster it wouldn’t be very clear to an outside observer.

I am not saying it’s legal or not, I have no idea, just that that is why I have become disillusioned with the idea of open source, and I am not convinced that a well-meaning license like GPL is a realistic safeguard against corporate exploitation.
