Browser fingerprinting is where JavaScript or other means are used to scrape uniquely identifying information from the browser metadata and functions such as how it draws a canvas object. In it's latest release Apple will defeat browser fingerprinting by making all Mac users look alike to advertisers and websites that use fingerprinting to track users. Apple can afford to do this as it doesn't have skin in the online advertising game.

Apple's money doesn't come from advertising. It comes from selling products to its customers, not selling its customers to marketers.
Now that Apple is using this as a differentiator in the market, there is a disincentive for Apple to track their users in the way that FB and Google do.
