Almost everyone uses Linux, thanks to its growing popularity in consumer electronics in everything from TVs to DVR (digital video recorders) to DVD recorders to you name it. Some companies, however, think that they can use Linux and open-source software for their products without releasing the source code or, in some cases, paying the creators. Wrong. The SFLC (Software Freedom Law Center) is lowering the boom on more than a dozen companies including Best Buy, Samsung, Westinghouse and JVC, all which have violated the GPL (GNU General Public License).
