Facebook claims new iPhone update disrupts online advertising business

/ / News

Facebook Inc. on Wednesday said privacy updates to Apple Inc.’s latest operating system have hindered the social-networking company’s ability to deliver targeted ads to iPhone owners when they use outside apps. The announcement, made in a note to app developers, says changes to iPhone’s new operating system, called iOS14, impact Facebook’s Audience Network business, which connects users’ Facebook identities with their off-platform activities. Facebook said the changes will “have a far-reaching impact on the developer ecosystem.” The flap is the latest between the two tech giants. Apple has criticized the data-collection operation that underpins Facebook’s multibillion-dollar advertising business.
