Why concentrate on intended use? More interesting is what, er, unanticipated value-add might be there.

Could a malicious actor create a blackmail-bot? It wouldn't even need to be that great - just something a little more believable than the "I took over your computer and videoed you masturbating" spam.

Could more subtle, targeted blackmail operation involve this data? There is a lot of this sort of thing in politics.

We know PIs, bail-bonders and other folks on the fuzzy LE/commercial coercion industry line were heavy users of realtime cellphone tracking. I imagine the more creative ones have considered the value of these data pits, too.
