But being made a Sith by Vitard means that Revan never turned to the dark side on his/her own. And what Kreia says is this, "Perhaps Revan never fell. The difference between a fall and a sacrifice is sometimes difficult, but I feel that Revan understood that difference, more than anyone knew. The galaxy would have fallen if Revan had not gone to war. Perhaps he became the dark lord out of necessity, to prevent a greater evil."
BioWare changes that and makes it so that Revan became the dark lord to serve the emperor. They disregarded a great idea and replaced it with their lame black and white bull****.
Making Revan a prisoner for 300 years, killing off the Exile cheaply and forcing canon down the players throats in an MMO? No thank you, sir.
Some of the fan fiction people came up with was ten times better than what BioWare produced, which is sad, because Bio are supposed to have professional writers.
