Google Joins Apple to Opt-out of Mobile Advertising IDs
10+ year adtech veteran here. This article is nonsense, written by someone without any industry experience.<p>Facebook has billions of users on several different apps. And people <i>log into these apps</i> to use them. FB, Instagram, Whatsapp. Cross-app tracking is not a big deal, they already know who you are.<p>The big hits are going to be a reduction in data collected by other apps fed to Facebook, and in measurement and attribution (like app install ads). If anything, it can actually strengthen their walled-garden data moat when advertisers realize that it&#x27;s still the most efficient way to reach users. Their last earnings report shows significant growth and is the opposite of a struggling business.
