Not that I'm aware of. The licenses you mentioned as "free" are copyleft licenses which require modifications to retain the same license terms. The rest are usually called permissive licenses, as they don't have such requirement. Nevertheless, both kinds of licenses are and AFAIK have always been considered FLOSS and I'm not aware of any controversy around that. The distinction came basically because of political reasons. The term "Free Software" is about user freedom; the term "Open Source" has been coined so you don't have to refer to scary freedoms when presenting practical aspects of FLOSS to businesses. That's more or less the whole reason why those are separate terms, and also why FSF doesn't like the latter one.
