You really want me to cite the existence of, what, Linux? OK. Linux exists[1].
Linux exists and is pervasively shipped in license-conforming form by hundreds and hundreds of vendors. Do I win now? Sorry, but my "argumentative" attitude is just exasperation. Open source is the rule, not the exception in the software world. And the license regimes that permit that work exceedingly well.
[1] Or chromium, or glibc, or clang, or git, or... It's literally a whole ecosystem of people working on these projects and shipping them in the expectation that they'll be used legitimately according to the license. And you... don't think that happens? Are we all just hallucinating?
