Gruber isn't non-critical of Apple's iPhone business either. He has consistently criticized them for how they're managing the AppStore, for instance.
However, because he also has deep insight into Apple's business and culture (probably better than any industry analyst), he understands the underlying reasoning and motivations, and so he doesn't just spout out ignorant rants nor pretends to know how to "easily" solve the problem, either.
Now, I might come off as a Gruber fanboy here, but just read up and you'll find that this is true. He speaks from humility and insight, and he doesn't serve up advice on how Apple should improve their business — in all respects — with a quick fix, like most other Apple critics do.
