Last time I checked, "Caster of Magic" is a mod for Master of Magic. It's based on the fan-made patch 'insecticide', by kyrub. Insecticide is very conservative about gameplay changes. I don't know about CoM (I didn't try it because I didn't like the change list), but kyrub actually scaled down some artificial AI bonuses because smarter behavior makes up for that.

Overall, I think the author of the article didn't research the unofficial patches very well.
