"Does the author really think that Apple put this much thought into not letting certain journalists into new coverage. "

Dunno about the author, but me? Absolutely, yes.

Not just Apple either. Probably every large business with a half functioning marketing and PR operation.

Quite right as well. Its their job. Present the product in the best light possible to maximize profits of the owners or share holders. That is the purpose of business.

I make no moral judgement. Its just raw capitalism. The trick is to know this and to never accept a single source, then make a judgement.
