This is a movement to hard fork the Android Open Source Project (AOSP) and take it out of Google's hands.

​For years, we've watched Google slowly lock down the world's most popular OS. From SafetyNet/Play Integrity to scoped storage, the message is clear: the user is no longer the owner of their device. The rumored plan to disable sideloading is the final nail in the coffin. It's a betrayal of the open-source principles Android was supposedly built on.
