In an interview with Recode's Kara Swisher and MSNBC's Chris Hayes, Cook expressed concerns about Facebook and other companies amassing what he called "detailed profiles" compiled from multiple sources.
He also suggested that the government needs to crack down on Facebook. "I think the best regulation is no regulation, is self-regulation," said Cook. "However, I think we're beyond that here."
Cook also questioned the use consumer data to sell advertisements. "The truth is, we could make a ton of money if we monetized our customer — if our customer was our product. We've elected not to do that," he said. Almost all of Apple's revenue comes from selling iPhones, iPads and other hardware.
Asked by Swisher what he would do if he were in Zuckerberg's position, Cook said pointedly: "I wouldn't be in this situation."
Facebook faces mounting pressure to explain how it let Cambridge Analytica, a data firm started by former White House adviser Steve Bannon and wealthy Republican donor Robert Mercer, "scrape" information for as many as 50 million Americans off its website. The data was then used to target political ads to Facebook users ahead of the 2016 presidential election.
Facebook CEO Mark Zuckerberg is likely to appear before Congress to answer questions about the Cambridge Analytica affair and the social network's data practices,.
Facebook on Wednesday said it would seek to give usershow outside firms use their data. The company has drawn fire for obtaining users' data through terms buried in fine print, making it harder for people to opt out.
It's not the first time Cook has spoken out against Facebook. Most recently, the executive said at a technology conference in China last weekend that he favors "well-crafted regulation" for data privacy, according to Bloomberg.
