Gruber is very pro a lot of things, but Apple fits in well with what he's championing in life. If he comes across as biased it's that he's enthusiastic about the same things Apple embraces.
If you switched the byline to someone else, like John Dvorak, and showed this to people they might have trouble refuting it once their ad-homeneim attack option is gone.
No, he comes off as biased because whenever Apple flip-flops in an opinion Gruber is always standing by to defend them, even when the switch is, by all standards, incoherent.
Four years ago Apple was all about claiming UI superiority through consistency. Now it's "old". If Apple had had tighter supervision on iOS UIs I'm sure Gruber would have never said what he did. This is but one example among many.
My problem is that Gruber is being hypocritical. Apple apparently can decide what to support in their browser and on their devices, but Google is required to support things in their browser based on other's demands?
