Out of curiosity I just tried what you just said. It showed me the location I was in over 3 months ago in a totally different city to the one I live in. I have since a) connected to over 5 different wifi points. b) been back to that city twice (however it showed me at the hotel I was at 3 months ago) I'm not overly concerned about that form of tracking.

What these guys did was solve a problem that many companies were trying to solve throughout the world for some time with regards to wireless data transmission.
They found the solution told everyone about it and then had their technology replicated everywhere.

Watch the video link in my post just after this if you want to hear the facts about why they wanted compensation for solving an issue noone else could.
