This raises another interesting point, if your interpretation is true.
 That paragraph doesn't mention that the copyright holder needs to
explicitly revoke rights, or even notice a violation -- it just
happens, the user loses the rights automatically.  I would guess that
every single person owning copyright to (L)GPL ffmpeg code now needs
to explicitly give him back the rights to distribute.  To distribute
on a single person's go-ahead, in this case, would still be copyright
