I disagree. Strongly. YOU may CHOOSE to share the information you mentioned (maybe in order to get some useful services). I don't. And even when I DO choose to share, I choose who with, I read their privacy policies and I take note of their past behaviours.

So, for example, I do use Google Latitude, sometimes (I only turn it on when I want it and I understand the risks). I do not use Google for mail, contacts, etc. Those are both conscious decisions -- someone else will make different choices. The fact that they make those choices does not mean that their data is now "public".

From the terms and conditions (thanks to Faheem for attaching them to the bug report) it sounds like they send IMSI. Now, why on earth would they do that? Will they be sending encryption triplets next?

Aha! I think you have worked it out!! They don't need any sort of privacy reputation to enter the building business! And they used to make car tyres and rubber boots so ceilings wouldn't be too much of a stretch.
