It's actually a pretty nifty allegory.
No, it's really not.
At least not in the sense of being a meaningful allegory contained with an a story which is entertaining and compelling on its own.
This episode is nothing but soapbox preaching, thinly veiled in technobabble. It's not about the message, it's about the way in which the message is conveyed. Telling a good story should always come first, the message second. When Trek does it in that order, Trek makes extremely compelling television that also effectively conveys a relevant societal message. When Trek resorts to preaching, the message doesn't have an impact, because people tune out the bad story too soon.
