Yes you can rescind. Re: CoC loving Linux programmers swear the GPLv2 is irrevocable. They are wrong. (As are the women they wish to empower).

If you lend (license) your lawnmower to BrucePerens, and receive nothing 
in return, and BrucePerens hires someone else to draw a star on your 
lawnmower, BrucePerens believes he can keep your lawnmower forever 
because he "relied" on your lease and , even though he paid you nothing 
and you never said you would not rescind the license (a default right of 
yours, you being the property owner).
