Glad to see a mobile OS taking action against Apps that are used for ad tracking. Might finally have to switch to an iPhone. I'm sure Google will follow soon like they've followed Apple's Safari with blocking third party cookies and one year certificate validity.Facebook representatives have reportedly reached out to key advertisers about how Apple's forthcoming ad tracking limitation in iOS 14 will affect them all.
Announced as a privacy feature, Apple's forthcoming iOS 14 will require users to choose whether or not to allow ad tracking. Facebook reportedly expects a significant number of users to refuse it, and has been trying to work with advertisers concerned at potential loss of revenue.
Ad tracking is the feature that lets an advertiser know that someone buying a product from a certain place online, was driven there by an ad in, for instance, a game. To facilitate it, Apple has a random device identifier tag called an IDFA (Identifier for Advertisers) which lets companies track the effectiveness of ads without gaining a user's personal data.
