The question at what point submissions can be revoked is a general one, not tied to CLAs, and it's come up in the past (eg. in Samba). The musing about whether the FSF owns copyright on stuff you haven't submitted seems both unimportant and an invitation to armchair lawyery.
Now, I don't like CLAs either, but this didn't really add any useful data. It read more like FSF-baiting :(

IMHO I didn't feel the article was really a beat-up. It might have brought up issues that have been raised before but I feel that those might be seen in a different light given the recent events mentioned. I do feel that "The question at what point submissions can be revoked is a general one, not tied to CLAs, and it's come up in the past" is indeed a valid point but I also feel that copyright assignment and when it occurs is an important issue which is worth mentioning when it arises. Please forgive me if I repeated myself in this post.
