1. Buy medication I never have bought or even searched for before at local pharmacy w/ credit card
2. Go to car, decide to test #Librem5 cellular by visiting my account on mobile.twitter.com
3. Immediately see ad for type of medication I bought!
No location tracking possible on this Librem 5 (used browser, not native twitter app), so either a crazy coincidence, or near-real-time reporting between CVS and #adtech w/ linking between my name, card, and twitter account.
@kyle There are many ways to track humans. Cameras can identify you by the way you are walking or the way your heartbeat can been measured or your face... Maybe you wear digital clock or cloth. However you moved by car - relatively fast - stopped around pharmacy for 5 min. Its not hard to guess where you are going to. Celltowers triangulate your position pretty exact and your Carrier has detailed info about every packet your phone transmits. - Still the exact medicine: Has your car Siri / Google
