I do wonder how many open source / free software projects have code contributed to them that is actually owned by Google (or some other corporation) and will it come back to bite anyone?
Yeah, but this points to someone who didn't get clearance so I wonder if it is a unique case. Also, I am actually thinking of some other companies. Thinking about it further, some projects want copyright assignment, so one wonders if some of those weren't done properly.
Actually, he did get clearance, that's not immediately apparant from his thread, but he was granted permission to release code into the Snap Framework under Google's copyright and an open source license.
