That would be the Noncommercial ("NC") clause, if Frath's got that as part  
of its CC license. SA just means that derivatives of the conlangs  
themselves need to be SA. As far as I know, it doesn't stop some someone  
 from bundling *unmodified* content into a commercial product royalty-free.  
If Joe Q Filmmaker wants to add lexicon to a SA conlang for specific  
dialog in his film (for instance), he'd just have to publish that lexicon  
somewhere under an SA license.
