Copyleft <i>is</i> those user-protecting restrictions. I&#x27;ll refrain from repeating myself.<p>By your &quot;fewer restrictions&quot; logic, permissive licenses would be the ones most copyleft. Again, the purpose of copyleft is proliferating &quot;freedom-respecting&quot; software, not amassing - open source. Code that is open, but you can&#x27;t utilize freely because of a locked-down device or a patent - &quot;misses the point&quot;. Preceding references emerged organically and... whoa.<p>Most GPLv2 bias which isn&#x27;t caused by Linux&#x27; licensing is due to the kind of FUD you&#x27;ve perpetuated in this thread, not any actual issue with GPLv3.
