Earlier quoted context omitted.
How is a Microsoft-authored app connecting to Google's YT servers comparable to an Apple-authored app connecting to Apple iMessage servers?
How does Google have the nerve to whine about iMessage after they used Youtube as a weapon to kill Windows Phone?
Do you think Google (or any organization) is capable of shame? I could extend your question to "How could Microsoft whine about Google shutting down its Youtube API access, while Microsoft was shaking down Android OEMs with secret patents and forciing them to make Windows phones as part of the (secret) settlement?" or "How can Apple ramp up its ad products when it rails against Google/Facebook ads?". The answer to all of those questions is self-interest.
