2 months and no response from Eben Moglen - Yes you can rescind your grant.

[vsnsdualce at memeware.net]

It has been 2 months. Eben Moglen has published no research.

Because there is nothing more to say: The GPLv2, as used by linux, is a 
bare license. It can be rescinded at the will of the grantor.

The regime that the FSF used, vis-a-vis the GPLv2, is essential: 
copyright transfers to a central repository entity that is sure not to 
rescind.

Linus chose not to adopt this regime.
He benefited by greatly increased developer contribution.
The price for that windfall was and is the retention of their 
traditional property rights by the property holders.

They can rescind at will.
They made no promise nor utterance to the contrary that can be relied 
upon.
They were paid no consideration.
There was no meeting of the minds.

Additionally the CoC regime itself is a license terms violation, being 
an additional restrictive term, as explained in the other analysis. 
(Similar to the GRSecurity license violation)
