#Google said it has no involvement of OEM's including app stores by default. To ship an #GooglePlay device, it has to comply with secret NDA'd "GMS Compliance", which requires OEMs to justify to Google pre-installed app store needs to access the same APIs that Play uses to install and uninstall apps. Somehow, I don't think Google will stop requiring OEMs be granted permission by Google to include the app stores of their choosing.
@taketwo I would love to see a leak of the GMS certification process, GMS Test Suite (GTS) and related policies. Some of the things that it covers can be gleaned from the websites of companies that provide GMS certification as a service, for example https://www.hexnode.com/blogs/gms-certification-is-it-really-necessary-for-android-devices/
