That's with mainstream phones, yes. But not with niche products that fail to launch. I have a Nexus Q. Even though it's more powerful and capable than the Chromecast in almost every way, rather than update it to support the new Chromecast protocol, they removed the code that even allowed it to work at all from YouTube and Play Music, effectively bricking it.

I don't think Android TV has ever gotten much love either.

Glass went from monthly updates to completely unsupported, practically overnight. That actually was being openly sold on the Play Store for a while too.

I'm not saying they haven't been on the ball with most of their mainstream products, I'm just saying you should bear in mind that they've let plenty of their failures just die on the table too.
