Two weeks ago, the one-click Cyanogenmod installer hit the Google Play store, making it possible to switch from the stock Android operating system to a more free, more open version without any special expertise. Yesterday, Google asked Cyanogenmod to remove the installer, because using it voids your device's warranty. I've downloaded other apps from the Play Store that root your device and void the warranty, so this seems like a very selective enforcement to me.
In any event, Cyanogenmod's installer can be "sideloaded" into your device without having to go through the Play Store (one of the advantages of Android is that it doesn't attempt to prevent you from installing unapproved software). Hundreds of thousands of people used the Play Store version, and we can hope that it remains in use, even without Google's official support.
They advised us to voluntarily remove the application, or they would be forced to remove it administratively. We have complied with their wishes while we wait for a more favorable resolution.
To those unfamiliar with the application, it has a single function – to guide users to enable “ADB”, a built in development and debugging tool, and then navigates the user to the desktop installer. The desktop application then performs the installation of the CyanogenMod on their Android device.
After reaching out to the Play team, their feedback was that though application itself is harmless, since it ‘encourages users to void their warranty’, it would not be allowed to remain in the store.
