Relevance of "Academics fear speaking freely in Canada" 

I'm not clear on what the relevance of the August 23 National Post article is.  It doesn't mention Kempling, and states that the academics are concerned over potential legal restrictions on freedom of speech.  There is certainly a clear connection to the human rights tribunal cases mentioned, but what's the connection to this one?  No legal action was ever taken against Kempling for his views, and the article doesn't deal with professional codes of conduct.
