copyleft software, not "free" software

> With hindsight, it's unfortunate that the originators of the free software term didn't talk about "software freedom" rather than "free software", which would have meant the same thing while avoiding the whole free beer/free speech ambiguity.

... and also avoided any copyleft/permissive ambiguity - thanks!

BTW "Software Freedom Conservancy" is an exceptionally clear name.

While their top goal seems to be copyleft enforcement, funny enough they don't seem to request copyright assignment before sending a patch. Their website also seems less focused on philosophy and more on getting copyleft things done but maybe that's just my impression.
