There is no evidence that this edition is any more important than any other.  The primary source manuscript is in the Paris Opera Library and any qualified scholar could have access to it to prepare an edition.  Several editions exist and are used for both performance and study. 
The score of this edition is for sale for 520 Euros.  The score of Verdi's Trovatore is available from Dover for 36 euros.  I hardly think that this edition would qualify as a "not-for-profit" enterprise.  However, you might have more information than I have on this.  
If you really feel that this information is important, then why don't you add it to the article, without the commercial link?  That way, the information is available without the possibility of conflict of interest and spam.
