FOSS 

FOSS is an acroymn which refers to Free and Open Source Software. A term nessicary to describe two releated entities, yet different and seperate in some important philosophies.

This acroymn has its origins when the Free Software Foundation proclaimed their GNU General Public License as not actually open source, even though it is considered an open source liscense and is compliant with the Open Source Definition as described by the Open Source Initiative.

The FOSS communities are related, and differ only in extreamly judgemental geek lexicon and proclamations.
