This article is not correct. Does Apple track user information? Yes, they just don't sell those data to adverisers but keep those information for themeselves and use it as advantage to sell their services and devices. The number of Facebook users doesn't mean anything because Facebook and Instagram are free services, there are a lot of inactive accounts and bot accounts. In order to publish their apps to app store they have to get approval from Apple and Google. So Apple is still the ultimate gatekeeper.
