AARRRRGGGGHHHH!!!!!!!! NOOO!!!! That's not freaking true!!!!Open-source software is a generic term applied to programs for which the source code is available -- but it may still cost money. Free software is a subset of open-source software and generally means that the software is available for use at no cost, subject to license agreements like the GNU General Public License. The Linux operating system, sometimes called the GNU Linux operating system, is free software.
