The "source" you provided was a simple URL. You noted no information about it at all, i.e. no writer, publisher, year of publication, it's origin, etc.

Regarding previous consideration of other commentaries as canon, they were only ever used in cases where they didn't contradict the games, or supported what was already present in the games. This Mantis one is clearly contradictory, and the game can't be claimed to have created a retcon because it never presented this info. Saying it is a retcon is misleading, and you yourself note in the Mantis article that it could imply a retcon.
