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 said Wednesday 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 than on the 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's iOS 14 update, which Apple says is designed to protect people's privacy, will require to ask users for permission to collect and share data using a unique code that identifies their iPhones and iPads.

Facebook said that because of this change, it will no longer collect the identifier for advertisers on its own apps for iOS 14 devices. It is also asking businesses to create a new ad account that is dedicated solely to running ads for apps for iOS 14 users in order to comply with Apple's new rules.

In Facebook's second-quarter earnings call last month, finance chief Dave Wehner said the company is “still trying to understand what these changes will look like and how they will impact us and the rest of the industry.

But the very least, it's going to make it harder for app developers and others to grow using ads on Facebook and elsewhere." He also called targeted ads “are a lifeline for small businesses, especially in a time of COVID." Apple, on the other hand, said it is intent on giving people more choice over how they want to be tracked by companies on the internet — and the ability to say no if they don't.
