IIRC they actually don't and it materially reduced Meta's profit when Apple rolled out the advertiser ID system.

"Facebook says Apple iOS privacy change will result in $10 billion revenue hit this year" (2022):

See also perhaps "It’s not Meta - its APPLE who have screwed us small advertisers":

That may have been true initially but meta has enough information to heuristically observe unidentified users and compare their behaviors with known consumers. It only takes a few actions to uniquely identify a consumer with a high degree of confidence.

  • Yes, it was temporary and Meta revenue and profit at all time high (before data center buildout).

  • Pretty sure Meta doesn't do that on iOS devices because that'll get you banned from the App Store. They just figured out ways to not need individual fingerprinting.
