We can just do the adult check thing the usual way.

It’s not about age. It’s about uniquely identifying everyone who uses a computer.
How is it uniquely identifying users if all that OS shares with programs is the age group? (that btw user chooses, can lie without problem)

Fingerprinting. Age, as well as factors like IP address, can be one more data point to individually identify a user with a certain number of accounts.

There’s also potential they changeover from “Enter your DOB” to “Show your driver’s license”, which they can collect much more data from.
