In classic Star Trek there was an episode entitled "The Return of the Archons" where the crew of the Enterprise beamed down to a planet where the starship "Archon" had last been reported, some time previously. They found themselves in a stagnated Victorian era society of people going mindlessly about their business, rattling off platitudes like "Peace be with you, Friend" to passers by. The society turned out to be controlled by a supercomputer which had taken on the name (and projected image) of Landrew (or Landru), its creator some millennia previously. Landrew stifled all attempts by individuals to exercise freedom and free-thought both through exercise of technology and through good members of "the Body", who ratted on anyone who digressed from accepted norms. Those who couldn't be "reabsorbed by the body" through mind control were eliminated. The story ends with Kirk winning a logical confrontation with the computer, arguing that instead of following its purpose of protecting the society, it had harmed it by stifling all creativity and personal growth within its ranks. The computer can't face the realisation that it has failed its programmer and shorts out (it happened a few times in classic Trek...)
One memorable moment was when the brainwashed ("absorbed") McCoy said something along the lines of: "Why are you talking in lowered voices? Members of the body don't whisper and plot!" (shouting): "You are not of the body! They are not of the body!"
I think Landrew's society is a better allegory for the Watchtower than the Borg - the Borg at least are dynamic and grow, albeit by theft. Landrew's society was stagnant, locked into Victorian era morals (with the notable exception of "Festival" - cf. a JW wedding reception with an open bar) and archaic modes of dress, dominated by a being masquerading behind the image of the society's founder and "the good of the body". Individualism could break out in Landrew's society but was quickly dealt with by re-absorption or elimination.
