In a blog post the social network giant is warning developers that IDFA requires users to opt in and that this will make IDFA essentially useless. Facebook’ apps on iOS 14 (e.g., Facebook, WhatsApp, Instagram, Messenger) will no longer collect users’ IDFA. Until now, advertising businesses can identify users cross apps with the IDFA and place targeted ads in other apps. This is what Facebook does with its Audience Network program. As Facebook exaplains in a blog post:
For developers and publishers using Audience Network, our ability to deliver targeted ads on iOS 14 will be limited. As a result, some iOS 14 users may not see any ads from Audience Network, while others may still see ads from us, but they’ll be less relevant. Because of advertisers’ reduced ability to accurately target and measure their campaigns, app developers and publishers should expect lower CPMs on Audience Network and likely other ad networks on iOS.
Depending on which side you stand on, this is either a good thing for you (regulators and privacy advocates) or a bad thing for your (advertisement businesses).
