Facebook (FB  ) acknowledged that Apple's (AAPL  ) new iOS 14 software could lead to a drop in its Audience Network advertising revenue. Facebook states that more than 1 million people see an Audience Network ad on their devices. The Audience Network allows developers a chance to target customers with ads based on their Facebook data. Facebook receives most of its revenue from advertisements, but the exact percentage remains unknown.

The new Apple upgrade plans to make it more difficult for advertisers to keep track of customers. It was always Apple's goal to protect the privacy of its customers but recent antitrust allegations, this change seems to be a ploy.

"I think there's probably 30% truth in that they're doing it for privacy reasons, and it's 70% that they're doing it because it's what's good for Apple," said Nick Jordan, founder of Narrative I/O, quoted by the Washington Post, which helps companies gather data for advertising. "It's a question for regulators and courts whether they should be able to wield the power they do over this ecosystem," he said. "They created it, but can they rule it with an iron fist?"

Facebook published a blog detailed with specific steps it will take to ensure it stays in line with the regulations outline by Apple. These steps will restrict the freedom that allows Facebook and other advertisers to target ads on Apple devices.

"We know this may severely impact publishers' ability to monetize through Audience Network on iOS 14, and, despite our best efforts, may render Audience Network so ineffective on iOS 14 that it may not make sense to offer it on iOS14 in the future," Facebook said in the blog post.

This isn't the first time Facebook and Apple have sparred over privacy rights violations. Apple CEO Tim Cook has made disparaging remarks in past about Facebook's monetization of personal information and Facebook CEO Mark Zuckerberg called out Apple for overpriced products. However, Apple and Facebook both face investigation by lawmakers for abuse of power in anticompetitive ways.
