Yeah the problem is that you only read the sentence you highlighted.
The important part was that MS should not give up on what was an innovative and amusing line of ads (much better than the Get a Mac stuff), just because a few Apple-obssessed bloggers don't think they'll work.

Who knows maybe they can pull this off. I really doubt it but who knows? There is probably going to be a ninja chicken involved, I think there is a ninja chicken in every ad by this ad agency. I think the public can really relate to that.
