You can't read Gruber in the same context you did five or six years ago. At this point he's an established journalisty blogger who depends on a network of sources, some of whom are within Apple Inc. That means, like most working journalists, he needs to consider the tone he takes with any individual article vs. what that article is going to do to his network of sources. The result is his writing still contains the smart incisive analysis it always has, but he also has to bend over backwards to make sure he's presenting what the the internal Apple take on the situation is. Compared to what you or I might say about Apple's behavior over a few beers, yeah, he comes off sounding like an apologist, but compare his coverage to what other in-the-tank tech writers say about Apple and he still comes off as an independent voice covering the company AND someone who can provide a level of context other people can't (details on Nitro's implementation)
