  "Targeted advertising" in the sense of real-world, physical targeting. Like, where should adverts be placed in the station to maximise exposure. That doesn't require and collection of data, and they have explicitly ruled out doing such collection.

    They already have, e.g. adverts that run in parts down escalators. If you know plenty of people go from one corridor to another, you could extend such segmentation across corridors. I imagine they can also do differential pricing of adverts across more of the stations with a better idea of footfall (though simple point footfall figures can be got in simpler ways), and indeed that is apparently part of what they're doing.
