@eri @linux_mclinuxface @shroomie There wasn't a CLA before the license change.
If a contributor didn't accept the license change (I doubt they asked anyone, we'd then have known for this happening well in advance), they're effectively violating the BSD license by not keeping copyright notices and clauses.
(Doesn't protects the source code though, because it's not copyleft)
