I've worked with the Safegraph data mentioned in the article. They draw a polygon around a set of geographic coordinates and tell you how many iPhones vs Androids we're in that polygon in a week and they associate that polygon+address with a named business. Yes, that polygon could be a doctor's office as the article raises but so what? There is nothing tying it to you/me/any person. It's a location-popularity index basically. I have a hard time coming up with a scenario where this is a threat to my liberty. The article especially at the end conflates tracking of persons with tracking of popularity, and is (imho) disappointingly fear-mongering.
