@johannhof pointed out that federated login intrinsically "identif[ies] that a user on one site is the
same person as a user on another site", which is how #2 defines navigational tracking. If we want to say that navigational tracking is always bad, we need some carve-out for cases where the user intentionally copies their identity using a navigation.
Alternatively, we could say that federated login is tracking, but a kind that's not bad. Then we might need yet another term to be the thing we think is bad.
