CoC loving Linux programmers swear the GPLv2 is irrevocable. They are wrong. (As are the women they wish to empower).

[william drescher]

"Consideration" can be in form of "
detrimental reliance." That means that you relied on the license 
and that reliance cost you something.

So if you spend money to pay programmers or if you spend time 
writing programs based on the license you have paid for the 
license.
