All this tracking is obviously one-sided. I might not mind it so much if I had access to sufficiently granular data to make it useful, such as automatic workout tracking. I'm sure they have the data and the AI to notice that I'm on foot/bike moving at a higher-than-normal pace and on one of my usual workout routes. Or, to provide nice detailed reports of my commute (min/max, variance, total time, etc.)... But no, the only data we get is rough, 'you visited store X yesterday, want to review it?', when I actually only visited the much smaller store nearby... There is already starting a backlash from this massively greedy -- in both data & money -- culture. It would not surprise me to see it overshoot and seriously cripple the industry if the participants don't become a bit more self-aware.
