I think everyone should be looking to balance their work effort against the payout of the job. They should also be changing jobs when the effort to reward ratio starts to become unfavorable compared to other jobs on the market.

The problem with the personality above is that the person isn't playing like a team (like you said) but as an individual maximizing their own visibility while loading their coworkers up with the review effort. They found an asymmetry to abuse (they generate text easily, coworkers get a lot of extra work to review it). They don't care what it costs their coworkers. They just like that it makes them look good.
