Do you think Debian should welcome embargoes for GPL compliance issues? Security embargoes are a huge pain, but one would hope that GPL violations by Linux distributions are much rarer events.
I'm asking because even with the GPLv3 or the Common Cure <https://github.com/gplcc/gplcc>, the 30-day period seems awfully short. I don't think even organizations that care a lot about GPL compliance (even formal compliance with exactly matching sources) will be able to address an accidental violation in that time period. Although the cure period only starts when notified by a copyright holder, with a public notice, other, less cooperating copyright holders might send a notification of their own and start another clock. Nothing can be done about GPLv2-only violations and the resulting license termination, of course.
