Are you suggesting that authors didn't know or understand that commercial exploitation of their OSS contributions was possible? If so, that is a complete misrepresentation of history. There has always been open-source licenses that disallowed commercial use. Authors have chosen not to use them, and instead chose licenses, such as MIT/GPL, that allowed commercial use. And there has always been commercial use of OSS. Big companies, small companies, tech companies, oil and gas companies, weapons manufacturers, banks, hardware companies, etc. They all use OSS and they all make a profit from it, without giving anything back to the people who originally wrote it. That's not an edge case or an unexpected consequence, it a fundamental tenet of free (as in freedom) software: You do not get to choose who uses it, or how they use it.
