Spare me any preposterous claims of corporate altruism; this wasn't enabled and encouraged by Apple to reduce page load times on the web. If Apple had their way, the web wouldn't even exist anymore.
It's been transparently obvious for years that Apple would like to replace the web with their own walled garden app ecosystem. Apple would also like to replace web ad networks such as AdSense with their iAd network. This is what we are seeing unfold currently. Their News app with its unblockable iAds is another tentacle of this plan.
