iOS 15 users: Does enabling this setting effectively mean your are proxying all your traffic through Apple servers? I don't understand how it would do what it says otherwise. #cososec
@voltronic That's exactly what it does. I get different IPs from whatsmyip.org in Safari with that on vs. Safari with that off (or Chrome.)
Note that it ONLY impacts the Safari browser app, not other apps web browsing, even though those use the Safari engine.
It does give a noticeable speed hit, though. I get ~800 Mbps with it off, ~330 Mbps with it on.
I believe that setting doesnโt use the proxy/vpn route but instead holds off on sending tracking data then uploads in aggregate. https://developer.apple.com/wwdc21/10033
@voltronic What's interesting is that it has an option to enable just for "trackers" - using that, I get my normal WiFi speed.
