This is interesting, if that's indeed the case then I'll publish my findings and encourage people to 1) fill similar requests, 2) fill requests for data deletion and ceasing of further collection. Hopefully eventually we'll get an option to opt-out via the web, like on http://myactivity.google.com/

Also, EU readers: why not ask your own provider today?

Apart from location I'm still concerned about actual data transferred via those networks (calls, text and data).
