Iโ€™m watching Joanna Stern's interview with Craig and Iโ€™m left wondering: What good is hiding the IDFA now if youโ€™d EVER used an app or service before?

If youโ€™ve logged in with an IDFA, that service simply has to keep a database entry that says, โ€œWas once IDFA 2204786โ€ and it happily continues to watch and share. 

Itโ€™s like an old phone number. Maybe I donโ€™t have a number any more, but if I used it in App X and App Y last year, if I log into App X today and do anything, X can still share with Y with high confidence that itโ€™s me doing that activity today.

Youโ€™re still going to know I was looking at that shirt unless I create brand new logins everywhere!!1!

Look, thatโ€™s not a reason not to hide that softball connection now, but itโ€™s going to help tomorrowโ€™s iOS users a lot more than todayโ€™s. The catโ€™s already out the bag, the horse out of the barn, the chicken has flown the coup. 

Our privacy is already shot. Youโ€™re welcome, later generations.
