I don't think anyone is saying Google must allow anonymous apps on their app store. Nor is there anything wrong with giving the user of a phone the option to only install apps which have been vouched for by some trusted third party. The problem is, Google wishes to take away my choice to install apps that don't follow their rules. And that's bullshit. It's my device, which I own. Nobody except me should be able to restrict what does and does not run on that device.
