Uh, what? Why shouldn't they be used?
Because Star Wars is as profound and morally complicated as a Disney movie. Even the best and most intricate Star Wars story, Timothy Zahn's Thrawn series, is still very black & white, good vs evil no matter how much it humanises the opponents.

Where does it contradict films? KOTOR takes place 4000 years BEFORE Episode One.
It contradicts the principle of the entire Star Wars universe. The Star Wars universe was built around the principle of Light Side vs Dark Side, Jedi vs Sith, Rebels vs Empire. Everything is just a big children's story where there's a very clear line between good and evil. Darth Vader is evil, until he suddenly changes and he's completely good again. There are no morally ambiguous acts anywhere in the movies including the prequels, Anakin may seem morally ambiguous, but he isn't. All his acts are either clearly evil or clearly good. The reason he seems morally ambiguous is that he sprinkles around good and evil acts, he doesn't sprinkle around any grey or ambiguous acts.
But besides the obvious spirit of the franchise, it also contradicts the canon of the franchise which clearly and repeatedly shows in absolutes that the Dark Side is evil, and the Light Side is good and that using the Dark SIde inevitably turns you eviiiiiiiile.
Then KoTOR2 comes along and goes 'Y'know, the force isn't good or evil, both sides can be used, Jedi aren't good either, everything is grey'.
That just doesn't work. Star Wars isn't the right setting for that kind of thing.
Aside from that, KoTOR2 does a pretty piss-poor job of conveying much of it story because so much was cut from the game. I'd recommend reading that SA thread, though, because it's pretty interesting to look at the game that way and you'll probably see tons of things you missed.
