In 2008 Sergey Brin and Larry Page saw the limo waiting, and instead chose to rollerblade to the Android unveiling. Sergey Brin, during the presentation, threw his G1 in the air to show off how his homemade application leveraged the accelerometer to see how high he'd thrown it

That use-case was never designed for when the sensor was added, and is every bit as hacky and fun as adding call recording with a loopbakc address

And that's the first problem: Android is no longer fun, and it's no longer for trying this hilariously stupid hacky method of doing what we, the users, want.

The second problem is an attitude of "Google's dialer has it built-in, why would one want a third-party dialer instead of Google's?"

Because we fucking can - or could, at least. The OS was designed to be as modular as possible, to the point where, while iOS still can't change their launcher, Android has had that option since day one. Setting aside Google casting themselves as the (not so) benevolent dictator of "Just use our apps exclusively. Life will be easier that way", closing off the modularity is antithecal to the Android experience that so many geeks fell in love with, and arguably made the platform what it is
