That's an interesting question. I don't have an expert opinion, but if I was to have some speculative fun I'd say that in the U.S. if you use the software without proper licensing then it would still be breaking civil copyright law. After all no one sells software, they sell EULAs that give a user license to use their copyrighted software. I'm not sure if a developer is allowed to intentionally leak their software without proper licensing and then claim that the user must still purchase a license to use the software. And if they openly admitted in court to having uploaded their software for anyone to download, I'd assume a judge would laugh them out of court.
