>It's wild to nitpick the licensing like this.

It's not a nitpick, the library was self-contradictory. It claimed to be copyleft while not allowing distributing modified copies by anyone other than the rights holder.

>There is hypocrisy here around internet archive, it's totally OK to store copy-write content on the archive, but its not OK when a company does so on their own.

That's right, because it was the company that broke their contract with their vendor by making publicly available source code when they didn't have permission to do that. If that software vendor has a problem with the IA they can issue a DMCA request.
