There's a lot of nonsense buried in safari and webkit. For example, loading certain URLs will deep link to on-device apps. If you surf to amazon urls in the browser, the amazon app will be notified. I'm pretty sure this is unblockable snooping people don't realize is going on.

So I think this is great news, maybe we get rid of nonsense like that.

However, I'll bet apple will make this japan specific just like eu laws don't affect their behavior in the US.

For example, a japanese iphone will always make a sound when you take a picture. If you leave the country, that will go away, unless you're in airplane mode and then it will start making sounds for every picture again. country-specific behavior.

I don't see why apple wouldn't do the same thing -- firefox works in japan, but not outside japan.
