I agree that since the article referenced that it was a "perfect storm of hard and soft product failings" meant, for me, that this was not a petulant rant with a sole aim to trash UA but rather a well thought-out review, documenting some serious issues UA has with Polaris.
I found some of the responses on here far more irritating than the article - taking a swipe at a blogger, mistaking the author of the article, etc. These are probably the same people who, themselves, complain about broken cashews and no PDB. Who knows.
The TPG blog has praised UA at times, including around the launch of Polaris; based on this experience I think it's fair game to write the article the way it was written.
