He isn't hard on Apple about the missing italic face in the same way he is about e.g. Microsoft's errors (he basically treats it as a regression for Apple to fix), and it's a gross distortion to characterize his verdict on the antenna as "This could be a fatal design flaw." Almost every mention of the antenna issue is cushioned with soothing positivity. He repeatedly states his belief that reception only drops when your reception is lousy to begin with, and overall he seems to think it's likely that the issue will be helped by a software patch, or maybe a small hardware fix. The "fatal design flaw" angle is brought up very briefly, immediately said to be unlikely, and then further softened by reiterating his belief that the issue doesn't affect your reception that much anyway.
I mean, I like Gruber. He's a good writer and has a lot of interesting insights and I actually value his opinion, but you'd have to be stark raving mad to read his blog and think, "Wow, this guy is kind of hard on Apple."
