Audience network just took a big hit from apples privacy policy changes. Google controls the entire ecosystem for many users and most of the ecosystem for pretty much all of them, so they can never get blindsided like Facebook did.
I saw this claim elsewhere in this thread as well, but I didn't really get it. Google is going be affected equally by iOS changes. Google does control the Android/Chrome ecosystem, but I don't see how Google could make any changes there that hurt Facebook because of antitrust concerns.
Facebook says the iOS changes are going to cost them $10 billion this year. Google blew past earnings and issued strong guidance last quarter.
