It's like Apple offering a default "privacy vpn", and lately now google too, it's really just a way for them to slurp your data as well what you're visiting, dns resolving, basically everything you do over the network. Even worse is apple enables it by default for all their devices, so all day long firewall logs for customers fill with "proxy avoidance" drops for apple proxy service as that's what a firewall should do in a corporate environment, treating this as data exfiltration.

What does Apple really do with that information? I at least know what Google or Microsoft is doing, by example of this article.

I just laugh as Apple users misplace their trust and think they're somehow secure for it buying an iphone, at least Microsoft users know the insecure mess they're stuck with.
