There is a big difference between removing support for something you once supported versus never supporting it at all. If Google never supported XMPP, we wouldn't be having this conversation. But removing XMPP support in favor of closed protocols raises eyebrows. It makes people wonder if the change was for the better, or just as a way to close out competitors. Similar to Google Reader. If they never had the product, no one would be complaining. But they did offer the product, it was so much better than the competition that it put the competition out of business, and then Google shut it down. That raises eyebrows. That makes people wonder if there's something malicious behind it. That's not to say they can never change their product lineup or discontinue products. But if they do, they have to answer questions like this. If there was no malicious intent behind removing XMPP support from their chat product, then everything is fine and the questions stop. We don't know, which is why regulators are investigating. On the Windows Phone part, you are blatantly misrepresenting what happened. It's not that Google refused to develop apps for Windows Phone, it's that they refused to develop apps for Windows Phone, then blocked Microsoft from developing their own apps for Google products, then blocked Windows Phones from accessing Google products through a web browser that was more than capable of displaying Google web apps. You could not access Google web apps on Windows Phones in any way, a limitation that was not applied to any other phone maker or any other phone. There is absolutely no defending that situation, Google played Microsoft hard and they played them dirty. Yes, Microsoft has done the exact same thing in the past and yes they deserved it, but remember: Microsoft was punished as an abusive monopolist.
