I had an idea regarding this. What if a new CC license was developed for open source projects where that code could only be used by union-participant companies/individuals?
That would be interesting, but it would probably only pressure small to midsize businesses without resources to just develop everything in-house anyway, and even then, only if it starts to comprise the majority of open source software
They would develop a tool based on ChatGPT/Copilot to automatically transform FOSS software into an obfuscated form such that they could invoke plausible deniability in court cases.
