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.
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.

Dude, FAANG still manage to do it, day in day out.
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":

I would be even more shocked if instead of adapting, they’ve continued to lose $10b a year
Wow that number is line an order of magnitude or more than I expected it would be
Won't someone please think of the poor advertisers? /s

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

Apple does not enforce the rules uniformly
