I think it's a little unfair. From my understanding, the move to make latest Maps free on Symbian is a licensing issue - the software was already built and there so it was matter of making it "free". It is not built or available on Maemo, and would therefore require resources to make it in the first place before it can be provided along with the handset.

I do have my suspicions, however, if it were available to be released today would Nokia hold it back to allow Sygic "first shot" so to speak.
