<h2>Philosophy of the GNU Project</h2>

<div class="table">
<div class="left-column">
<p><em>Free software</em> means that the software's users have
freedom. (The issue is not about price.) We developed the GNU
operating system so that users can have freedom in their
computing.</p>
<p>Specifically, free software means users have
the <a href="/philosophy/free-sw.html">four essential freedoms</a>:
(0) to run the program, (1) to study and change the program in source
code form, (2) to redistribute exact copies, and (3) to distribute
modified versions.</p>
<p>Software differs from material objects—such as chairs,
sandwiches, and gasoline—in that it can be copied and changed
much more easily. These facilities are why software is useful; we
believe a program's users should be free to take advantage of them,
not solely its developer.</p>
