Governments are trying to ban #privacy by banning private messages.
Googles move to ban "side loading" is part of this. Once a law banning private messages can pass Google will enforce it.
The next stage (IMHO) will be a law banning non Secure Boot OS's. Secure Boot will be on by default and only authorized OS's will be able to boot. Part of the process for registering an OS will be to prove that it can block non authorized apps.
That is how the digital prison will be built
