Apple, Google, Facebook already track everyone and everything they can: all these gps, wifi, Bluetooth and even ultrasound trackers built into smartphones exist

Apple, Google, Facebook already track everyone and everything they can: all these gps, wifi, Bluetooth and even ultrasound trackers built into smartphones exist only for one purpose. After all, they are in the business of building accurate user profiles and selling ads to them. What they do need is ability to do this openly, so they're trying to leverage the epidemics to legalize their business (ATM it's in the grey area: kinda legal, but amoral).
