133    <p>In the rest of this article we explain more precisely how far the

157    <p>For example, if the code arbitrarily rejects certain meaningful
158    inputs&mdash;or even fails unconditionally&mdash;that may make the
159    program less useful, perhaps even totally useless, but it does not
160    deny users the freedom to run the program, so it does not conflict
161    with freedom 0.  If the program is free, the users can overcome the
162    loss of usefulness, because freedoms 1 and 3 permit users and
163    communities to make and distribute modified versions without the
164    arbitrary nuisance code.</p>
