It's to stop everyone trying to join the server and thus lagging it to death, the server list doesn't show if the server is listening, dedicated or passworded, so people are just trying to join randomly so there's heavy load on the servers, the only decent game you'll get out of NS2 right now is a passworded server, open servers get lagged out by all the join requests.
Some passworded servers listed here; <a href="http://www.unknownworlds.com/forums/index.php?showtopic=110474" target="_blank">http://www.unknownworlds.com/forums/index....howtopic=110474</a>
That server listing thread should be webbed tbh, atleast temporarily until they fix this. So people can grab the passwords easier and actually bugtest/try the game out :)
