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 That is freaky. Is it possible that the web page grabbed your location data from the phone somehow without asking? That still doesn't explain the specific med, unless it is very common/sex related. That might make the coincidence more likely.
