Eric Kress mentioned in the latest
@DeconFun podcast that Apple may be bringing back the IDFA. I don’t think that’s likely, and here’s why:
1) Apple is extremely serious about privacy. The recent privacy-focused billboard campaign is just the latest example. Privacy is a core theme at every
#WWDC, and Apple is deliberate about limiting who gets access to user data.
2) Reversing ATT and restoring unrestricted IDFA access would undermine that entire narrative. The IDFA is essentially a persistent advertising identifier that allows advertisers to recognize users across apps with a high degree of certainty. Fingerprinting can achieve something similar, but it’s generally less accurate and less persistent.
3) The speculation likely stems from regulatory pressure in Europe, where Apple has faced accusations that App Tracking Transparency is anti-competitive. There have been rumors that ATT could be modified or limited in Europe, but even if that happened, Europe accounts for less than 30% of global mobile advertising spend. That would be very different from a global rollback.
4) Apple has already absorbed substantial regulatory fines related to these issues. For companies the size of Apple, Meta, or Google, such fines are rarely large enough on their own to drive a complete reversal of a major strategic initiative.
5) Even before considering Apple’s position, privacy regulations such as GDPR and CCPA would continue to limit how advertising identifiers can be used. It’s also worth noting that IDFA access never disappeared entirely—users can still opt in, and a meaningful percentage of installs continue to share their IDFA with advertisers.
For these reasons, I don’t see Apple bringing back unrestricted IDFA access anytime soon.
What seems more plausible is that Apple recognizes SKAN/AAK haven’t fully solved mobile measurement. Rather than rushing out incremental changes, they may be rebuilding parts of the framework before announcing a broader update.
That could explain why they stayed largely silent on attribution and measurement during this year’s WWDC.
