Funny thing is that Google does the same thing all the time. Back when Microsoft released Windows phone, they had made a few really amazing apps. One of them was their email app. Google went out of their way to ensure Gmail would never work on it past the basic functions of reading and sending email. They also pretty much forbid YouTube from working on windows phones.
The email thing stuck out the most because Google announced they were dropping support to whatever protocol Microsoft was using to communicate with Gmail servers, then Microsoft announced they would use a different protocol and next week Google went "oh right we are also dropping support for this other protocol".
