This is a great idea but it kind of falls short. Elaboration with example: LinkedIn is notarious for swiping up any data points that it can find. Your carrier, your GPS location, etc. As long as there are two or more data points to successfully tie you to that id, it's already game over. It'll just be added to your "targeted advertising profile" and, given the wrong company getting ahold of it (looking at you, Equifax), sold/traded on the advertising market to third-party advertisers to build better profiles because... ...advertising dollars? Anyways, the premise is cool but I think - without addressing the dragnet that is targeted advertising - it'll just be a minor inconvenience, which will be conquered over time with the collection of enough data points to tie it back to the "you" that they already know. ...unless you start-off with a brand new phone (new IMEI) and don't associate any old accounts with it, that is.
