Re: Google Play
Started out as a store, but now is the framework for -everything-. It started out as a package manager, but eventually a lot of code that should be separate daemons got pulled into it. It looks like Google's intention is that Google Play Services becomes the entire ABI/API for 3rd party packages ("apps") to run.
It could be a well-intentioned, if misguided, attempt at reigning in misbehaving apps. But since its one of the few Google Proprietary binaries in Android, I am a bit more cynical and believe that Google's motivation is to pull as much away from the OpenSource parts so that they can gain 100% control over Android.
I wouldn't be surprised if in the next few years, Android becomes nothing more than a Linux Kernel, a massive binary module for interfacing with hardware correctly, the Google Play binary blob to act as the entirety of the User Mode OS components, and a monolithic Shared Library. Although the more cynical part of me believes that they'll jettison the Linux Kernel entirely and roll their own so they no longer have to comply with any Open Source licenses.
