Guessing here: Mozilla has a location service, fed by volunteers/contributors.
One way to contribute is by installing the MozStumbler app.
It seems the author contributes and is now disappointed about the inability to download the full dataset and pouts.
I would be interested in the full dataset myself, fail to see the why Mozilla guys are evil if they don't provide me the information about wifi names around the world.
I think the author is complaining about the opposite: Mozilla is now making available GPS coordinates from volunteer's contributions, which could be used to determine where a volunteer lives.
