A freetard is a unyielding proponent of Free and Open Source Software (FOSS) like the linux operating system. They make no apologies for going on 10 minute rants about the importance of their impeccable values like "not paying for things" and "sticking it to the man".
All freetards are self-righteous know-it-alls who get it off to pointing out people misusing 'their' and 'there', although most of them are college dropouts because instead of doing their homework they spent all of their time trying to get WoW and Ventrilo to work in WINE.
Normal Person: Writing this paper tonight is going to suck.
Freetard: You should use the new Open Office 6.00 on Ubuntu 12.4: Raging Rhinosaurus. It's like a million times better than Word and XP and once you learn how to use BASH and VI and shell scripting and python scripting and the C programming language and x86 instructions you'll be way more productive using your computer.
Normal Person: Gasoline is getting expensive.
Freetard: WELL MAYBE IF COMPANIES LIKE MICROSOFT DIDN'T EXPLOIT THE MONOPOLIES THEY HOLD IN THE COMPUTING MARKET WE WOULDN'T BE PAYING SO MUCH, HMMM????
