Given that it's obviously possible to independently agree with most of what Apple does and think that that what they are doing will be successful (which in reality has turned out to be the case), what exactly is it you're accusing Gruber of?
He's now a "trusted reviewer" who is given access to pre-release units. That helps him write these articles before anyone else, which helps him get page views and eventually revenue. Therefore, he is corrupted. Given how Apple treats its reviewers, it is completely reasonable to believe that he might lose his "trusted reviewer" status if he wrote a negative review of a new product. He is not independent, so his reviews cannot be seen as independent.
I'm accusing him of being like "Apple makes you feel good, you should admit it": Apple doesn't make me feel good, their phones are too tiny, they look pretty but I'm sick and tired of their design, they cheat with their prices, they abuse software developers.
Their software is easy and intuitive to use but is too much rigid for my tastes.
IMHO he speaks like if people with my opinion shouldn't exist.
