FYI Safari has been doing this (also enabled by default) for years on all Apple platforms.

To disable it on macOS: Safari > Preferences/Settings > Advanced > Uncheck "Allow privacy-preserving measurement of ad effectiveness"

To disable it on iOS: Settings > Safari > Advanced (scroll all the way down) > Turn off "Privacy Preserving Ad Measurement"

In French it is deceptively named too. The explanation on official website is no better.

I always knew that safari is no better than other browsers, but the overt deception is a new low.

Hang on. What does it mean to disable this?

1. Does it disable measurement?

- or -

2. Does it disable the privacy-preserving feature, i.e., enable tracking?

What I really want to know: is it better for me to check the box or not?

Yes
