Apple privacy changes will muck up online ads: Facebook

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.
