> Even if Chrome had push notification on iOS

This is what I said. And this applies to rest of the paragraph. Also open standard has absolutely nothing to do with this, and that was exactly my point. You guys think just because it's open standard it's all open and good, but my point was it is not. The reality is Google and Apple are effectively duopoly when it comes to anything push notification related (GCM is the gatekeeper for Android, APNS is the gatekeeper for iOS). So it doesn't matter if a technology is open standard, it wouldn't even matter if it was completely open source. The reality is your push MUST go through either Apple or Google.
