Facebook: Appleprivacy will mu ck up online ads

Facebook is pushing back on new Apple privacy rules for its mobile devices— and putting app developers in the middle.

Apple will soon require apps to ask users for permission to collect data on what devices they are using and to let ads follow them around on the internet. The social network saidWednesday that those rules could reduce what apps can earn by advertising through Facebook’s audience network.

Facebook said it expects “less impact” on its own advertising revenue thanonthe ad-supported businesses that rely on its audience network to promote their apps. The audience network allows Facebook and Instagram advertisers to place their ads elsewhere on the internet.

Apple says the latest version of its mobile operating system, iOS 14, is designed to protect people’s privacy. It will require apps to ask users for permission to collect and share data using a unique code that identifies their iPhones and iPads. The update is due later this fall.

Facebook said that because of this change, it will no longer collect the identifier for advertisers on its ownapps for iOS 14 devices.
