I don't have any issue with that kind of technology, for what it's worth. You're only seeing how people use your site so you can figure out how you might tweak things, or understand what you need to do less of if you're scaring people away. It has practically nothing in common with the invasive tracking and advertising that follows you all across the internet, the likes that Google and Facebook involve themselves with at a scale beyond human comprehension.
Anyway, every page here is served with the
Permissions-Policy: interest-cohort=() header set. There is a valid argument that this still presents a datapoint that can be tracked, but since the change is happening server-side, it is less useful than if you sent the same thing from your browser in every request, adding to your unique fingerprint (as with
Do-Not-Track, an abject failure of a standard4).
