This is absurd. That data isn't worth anything, let alone to make up for the investment in these things. No one cares that you turn off your lights at 9:43, or that you are at slightly more risk for diabetes. At least not advertisers or the government. And the government isn't paying for this stuff anyways, they just get a court order to take it for free.

If you are so afraid of data gathering it's pretty much impossible to do a lot of technologies. I can understand being against centralization and sending that data over a network to third parties. But even that is necessary in order to improve the product. You want your self driving car to have billions of hours of experience behind it, right?
