Quite an odd thing has happened. A software author as released a repo under GPL 3.0 license
But inside that repo is code that the author doesn't own in any way and has no license. Now when people fork this repo their project will be under GPL 3.0 and using the code they do not know is stolen.
I'm wondering whos responsible for this code if people start using it? Can the people using it that think its under GPL in any way get in trouble for it or be made to remove it from their projects?
