I think Gruber's pieces about Apple are mostly useless, because he always seems heavily biased. Compare that to e.g. the ATP podcast, which is hosted by Apple fans but seems to contain more criticism and less apologism.
It's no surprise that Apple executives give him all kinds of exclusives.
Casey Liss, however, is just a cheerleader who would rather self-flagellate about his unworthiness to see Apple's blinding genius.
Marco's problematic/annoying in his own way, but Casey is aggressively... status quo???
