Exactly. It is not mandatory to go around - merely an alert. To continue with landing or go-around is a judgement call. Although not ideal, one can land 4000' down a long runway and be perfectly safe.
Apparently company SOP was that the pilots abort/reject the landing when getting a RAAS alert. No option. That's the point here. These pilots had apparently been trained/conditioned to be system operators and procedure monkeys. They were neither trained nor permitted to be thinking pilots.
