Whether MIT-type licences give more freedom than copyleft is very disputable, since they make it extremely easy to lose. But you are right that terms like ‘free’ or ‘libre’ are in no way restricted to copyleft.

I think they're saying that "Libre" typically implies Copyleft, with a GPL or AGPL or MPL License. Something that (in some cases) forces you to make your changes available.

LibreOffice, for example, is Mozilla Public Licensed, which is a weak copyleft, like LGPL (I think).

French native here. Libre means free in the sense of freedom, not in the sense of free as in free beer (the term for that is “gratuit”)
