These are good definitions but the original post wasn't referring to people not taking into account the philosophical part of free software, unless it really meant "copyleft".

A permissive licence doesn't really transmit the intent of the author, philosophy or not (it doesn't really matter, the licence is the same).

A copyleft licence, on the other hand, backs the philosophy behind free software via the actual licence.

But you are right, it should be "copyleft vs permissive open source".
