Tracking in this context involves cross-organizational sharing of user information, usually information behavior in particular. So it isn't that Google has my location data or that Ticketmaster knows I've been to a heavy metal concert - it is that Google finds out I was at a Ticketmaster heavy metal concert.

I disagree that it's cross organisational. OPs question was "is tracking useful" and the article is talking about sharing info between apps.

Being logged into Facebook messenger because I'm logged into the Facebook app, gmail having access to info from gcal, Ticketmaster having access to livenation preferences are all examples of sharing within the same organisarion that benefit a user.
