Most people consider licenses to derive their power from copyright.  afaik,
under copyright laws, independedt creators are not infringers.  this is
different from either trademark or patent.  otoh, copyright does not usually
protect function, instead protecting the "useful arts," so what this is
implies is difficult to say.  probably, a truly independent creator is fine.
