That's not as far as it goes, either -- if the software required to set up and maintain a geolocation database is free and open source, then anybody who does not trust the central provider can set up a dedicated machine with any desired level of security and privacy measures taken.
<br><br>There are some who would not think twice about letting their location be known to those that they list as friends -- users of Twitter and similar services come to mind immediately. At the same time - thanks to The Magic of Free Software - corporate users, journalists, and privacy-minded individuals can keep close tabs on what happens to their information.
<br><br>On that note, nothing stops servers running the same sort of geolocation databases from networking, either. If I host such a database on my own trusted machine in order to increase my privacy, I could still export choice data points (once per day, or upon special request, for instance) to a public database where anybody on my friends list can get at them. That way, I can carefully restrict the ability of any third party to amass information about me, while still selectively geonetworking with my friends.
