(Business Insider) Apple is making it harder for companies to track people’s data across apps — and Facebook says it could have devastating effects on part of its business.
On Wednesday, the Silicon Valley-headquartered social-networking giant published a blog post decrying changes Apple has planned for its iOS 14 mobile operating system. Apple intends to prevent apps from tracking users using their unique device identifier, or IDFA, without their explicit permission — something that Facebook’s Audience Network uses to personalize advertising in third-party apps.
