Thanks for the pointer, Mike.  Interesting post.  I do have a question
on how FSF will react, since I'm quite sure they will say the VP8 license
patent grant is GPLv2 incompatible for the same reason as Apache 2.0, and I wonder if they will say VP8
is GPLv3 incompatible.  GPLv3 defensive suspension is triggered when a
licensee initiates patent litigation against other licensees.  VP8 defensive suspension
is triggered when a licensee, a licensee's exclusive patent licensee, or the licensee's agent
initiates patent litigation, so VP8's defensive suspension clause seems broader in scope
than GPLv3's.

I'm sure FSF will have an opinion.
