I agree that Gruber is leaning a lot towards Cupertino, but when it comes to open Web standards he's always been praising Google's approaches and had critics for Apple's Safari and WebKit approach.

Let's not start pointing fingers about being hypocritical, tho, otherwise I would really hear for example how exactly is Google stance on openness not hypocritical. (I know you didn't name Google directly, but it's the easiest example)

iOS apps being a walled garden doesn't really have anything to do with the open web. Apple has long embraced the open web, so there's nothing hypocritical about this.
