This is beyond what we're talking about though, you're referring to copyright infringement. I'm referring to an open source licensed software that ALLOWS commercial use, the only requirement is attribution.

Your example only makes sense if the company stole the code from a proprietary repo, like a hostile former employee.

That analogy only works if there was a place you could signup for free to allow you to host and sell those files.

As-is, it's so far off it's useless. Even though both situations involve copyright in some manner.
