Apple's Chief Executive Tim Cook said Monday that talk of regulating technology companies is "fair" — even though he disagrees with it — because issues around privacy have "gotten totally out of control."

"Generally, for me, I'm not a big fan of regulation, I think self-regulation is the best," Cook said in a CNN interview. "But when it's not working, and in some cases it's not working, you have to ask yourself what form of regulation might be good. And I think it's a fair question many people are asking at this point."

He added: "I think the privacy thing has gotten totally out of control and I think most people are not aware of who is tracking them, how much they're being tracked and sort of the large amounts of detailed data that are out there about them."
