Backing your opinions up with studies is great. There sure are plenty of reasons (other than quality, which is the elephant in the room IMHO) that Gruber might sometimes find himself on HN.

But your analysis is more about why any article of his can qualify. Wouldn't it be better to judge this individual piece on its merits instead of pleading the general case?

If you label each of his articles as "Controversial; Pro-Apple" you run a risk of forgetting to read them. Today's piece should count against that label, not reaffirm it.
