I think people should be free to play what they prefer.
I do prefer OA, but I would not say that "quake live sucks", like you did.
It's a different game, with a different mood. It has got some good things (e.g. cylindric hitboxes, good looking maps...), and various bad things (no mod support, account purged after 180 days of inactivity, no multiplatform anymore, etc.). OA is about FREEDOM, Quake Live focuses on other aspects.
Surely I encourage people to play OA, but I don't discourage them to try other games, too.
PS: About other players' models in QL, go to Game Settings -> Advanced -> Team Options, and disable "force team model" and "force anemy model", if you wish!
