There is no DMCA basis for mentioning a third parties trademarked names in a review (there is in commercials you can't say "Cheerios" unless General Mills is ok with it, but you can say "That O shaped cereal", but no such restrictions editorial). Further the complaint is specious. Further the filing of a counter notice takes little time. (I can't see anyone pursuing the alleged infringement in court).

A simpler explanation for me, is a manufactured controversy to get use rage views to drive traffic to a reviews site (which lives and dies by its traffic numbers).

I'm taking a wait and see attitude here.
