Facebook warns publishers that Apple's upcoming privacy changes in iOS 14, which clamp down on ad tracking IDFA usage, will make Audience Network less effective
Facebook is warning advertisers that they can expect weaker ad performance from iPhone users once iOS 14 comes out next month …
Axios Sara Fischer
Context & Ripple Effects
This warning lands weeks after reporting that Apple Advertising appears to be on by default in iOS 14 while rival networks must ask users for permission to track — an asymmetry that frames why Facebook is flagging Audience Network damage now rather than waiting for launch.
The arc escalates from here: by December Facebook is running full-page newspaper ads attacking Apple and claiming the changes hurt small businesses, and by January experts are describing App Tracking Transparency as a threat to Facebook's core business across more than 85K iOS apps. This Axios piece is the earliest signal that the blast radius extends beyond Facebook's own feed to every publisher monetizing through Audience Network.
First-order effects
- Publishers earning revenue through Facebook's Audience Network face weaker ad performance on iPhones once iOS 14 ships next month, because the IDFA restrictions degrade the targeting that prices their inventory.
Second-order effects
- Advertisers and ad networks are forced to develop replacement targeting methods that don't depend on IDFA, as the broader industry braces for the change; Facebook simultaneously shifts to a public-pressure campaign against Apple.
Third-order effects
- Control of the tracking identifier gives the OS owner structural pricing power: Apple's own ad product runs by default while competitors need opt-in consent, pushing mobile ad economics toward platforms that own the access layer — a shift that ultimately reaches Facebook's core data collection, not just its network business.
The trend: Mobile advertising is being restructured around OS-gatekeeper privacy defaults, concentrating advantage in first-party platform ad businesses at the expense of third-party tracking networks.

In the forthcoming version of iOS, @Apple is simply switching from an obscure opt-out system for apps that want to track users across the web to an explicit opt-in system. At last! In my view, we should have a law requiring explicit opt-ins for the collection of personal data. ht…

It should not be Apple's responsibility to enforce ethical practices industry-wise, but that's where we are, and I'm here for it. Your business model should not rely on tracking users across properties you don't own. Sorry. https://twitter.com/...

A reminder that Facebook's revenue model is taking your content, or journalist's content, selling ads against it, and not paying you, or the journalists. You should get half of every ad sold against your content. https://www.cnbc.com/...

If Facebook thinks it can benefit from the pro-developer/anti-Apple sentiment many have right now regarding App Store rules, I think it miscalculated. I'm even more excited about iOS 14 now that I know this kind of stuff won't be possible. https://www.wsj.com/...

@samfbiddle This is no defense of FB, but framing the move as protecting the individual is probably doing too much of Apple's bidding. Especially given the boost this will give to Apple's own ads business.

I mean it's obviously true and we knew this was coming since iOS 14 was announced, but what do you think you're saying about your company when things that protect an individual harm your business so drastically that you need to issue a warning?

Apple and Google use control of the dominant browser and (in the USA) the dominant mobile platform to change what privacy looks like. The privacy regulator and the competition regulator should probably get in a room.

That's good for people who care about privacy. That's bad for Facebook, and probably Google, and also for other people who rely on targeted advertising. Facebook thinks it can essentially sidestep Apple's move, though it's unclear what Apple will do in response.

A lot going on here so I'll try to thread some of it for you. For the ad tech folks: Facebook is going to drop IDFA in iOS 14. For the rest of you: Apple is making it *much* harder to advertisers/publishers/ad tech ecosystem to hoover up information about you.
