@hayden Our Sandboxed Google Play compatibility layer is fully open source. microG exists to provide closed source Google Play libraries included by apps which is little different from the purpose of our approach. microG does not avoid closed source code, it exists to run closed source code. microG has poor security practices, low quality code and a poor approach to most of what it implements. We'll never add any support for using microG. microG also fundamentally requires privileged access.

@hayden GrapheneOS does not include an implementation of Google Play and does not connect to Google servers by default. It includes our own reimplementations of substantial Google Mobile Services features and that will continue to expand. We also have our own approach to providing compatibility with apps depending on Google Play services without needing it. We provide compatibility with Google Play services and Google Play Store as regular sandboxed apps but are expanding our support without it.
