"Free as in Beer" a term very familiar with
GNU/Linux users.
RMS says, "Think free software, not free as in beer", but I disagree. Free
beer is one of the greatest things that exists on the planet. If something is "Free as in Beer" it is of the utmost of freedom almost in the realm of liberty. A great thing for free is nothing to shake a stick at. Thus
GNU/Linux is "Free as in Beer" because not only is free
beer a great thing but
GNU/Linux is just as vital as life.
