I&#x27;m assuming &#x27;burntsushi is familiar with that line of argument, and disagrees about the philosophical meaning of &quot;perpetual freedom of users&quot; here. :) I think it&#x27;s disingenuous to claim that someone doesn&#x27;t care about freedom when they care about it under a different worldview (and also disingenuous, on the other side, to respond as if your worldview was the only one.) You both know what copyleft is and that some people prefer simple permissive licenses, I&#x27;m pretty sure.
