5: What are FSF, LPF, OSF, GNU, RMS, FTP, and GPL?

  FSF == Free Software Foundation
  LPF == League for Programming Freedom
  OSF == Open Software Foundation
  GNU == GNU's Not Unix
  RMS == Richard Matthew Stallman
  FTP == File Transfer Protocol
  GPL == GNU General Public License

  NOTE: Avoid confusing the FSF, the LPF, and the OSF.  The LPF opposes
  look-and-feel copyrights and software patents.  The FSF aims to make high
  quality free software available for everyone.  The OSF is a consortium of
  computer vendors which develops commercial software for Unix systems.

  NOTE: The word "free" in the title of the Free Software Foundation refers
  to "freedom," not "zero dollars."  Anyone can charge any price for
  GPL-covered software that they want to.  However, in practice, the
  freedom enforced by the GPL leads to low prices, because you can always
  get the software for less money from someone else, because everyone has
  the right to resell or give away GPL-covered software.
