I was pointed at links indicating that they knew they were doing it, I wasn't pointed at any links indicating that the new files in the tarball weren't GPLv3 when the notices on them say they are.
Are you claiming these new files are "mere aggregation"? The FSF is claiming that the old files weren't "complete source", and that they had to add GPLv3 files to make complete source, and that if you add GPLv3 files to a GPLv2 or later program the result is that the whole can only be distributed under the terms of GPLv3.
