Except this has all played out before. Consumers do what they are told to do. If a website says install this app in order to use it they will. If an app says approve this permission to use this app they will. And so you will inevitably end up with websites that only support Chrome which will increase its market share up until the point it is an IE style monopoly. And aspects like the cost of testing apps/sites on multiple diverging browsers will further entrench this monopoly. People go on about how this is great for competition as they can finally install Firefox etc. No. This is going to cement Google's control over the browser market and wipe out third party browsers like Firefox for good. And then we will end up with pro-advertising features that are built into the browser that you can't block.
