</div>How do you reconcile your interpretation with that of the FSF, which<br>
says "Therefore, accessibility of source code is a necessary condition<br>
<div class="im">for free software. Obfuscated “source code” is not real source code<br>
</div>and does not count as source code."? Also, I don't see anything in<br>
the GPL about "file formats."<br>
<br>
(I'm assuming that we agree that obfuscated source code can be<br>
distributed in the same "file format" as regular source: text.)<br>
