I think there's quite a distinction to be made between the people who did their best to survive under the East German system and the people who actively participated in establishing and maintaining that system.
Consider 1984 as being targeted at those who would otherwise be influenced by equally-simplistic totalitarian ideologies, and who might otherwise be led to collaborate with the equivalent the Stasi in the belief that they were doing good.
There was - and is - an unfortunately large population of such people, and I can't find much fault in Orwell's intention to shrink its ranks.
