Indeed, this is such a central point that it's made clear in the first chapter:
The telescreen received and transmitted simultaneously. Any sound that Winston made, above the level of a very low whisper, would be picked up by it, moreover, so long as he remained within the field of vision which the metal plaque commanded, he could be seen as well as heard. There was of course no way of knowing whether you were being watched at any given moment. How often, or on what system, the Thought Police plugged in on any individual wire was guesswork. It was even conceivable that they watched everybody all the time. But at any rate they could plug in your wire whenever they wanted to. You had to live--did live, from habit that became instinct--in the assumption that every sound you made was overheard, and, except in darkness, every movement scrutinized.
Remarkable that Asimov could overlook this.
The review seems completely consumed by professional bitterness to the point where it becomes laughable. By the 1980s the methods of KGB, Stasi, Securitate etc. were well known in the west; how can he put this on paper and not realize he was being a complete fool:
> [the governmnet in 1984] has a system of volunteer spies in which children report on their parents, and neighbours on each other. This cannot possibly work well since eventually everyone reports everyone else and it all has to be abandoned.
In fact, the human powered system of total state surveillance worked remarkably well, it was one of the few things that did work in most communist countries - because it was paramount for state security and enormous resources were dedicated to it.
In every block of flats, every factory floor, every friend circle there was an informer who wrote down weekly reports about who is making political jokes, who is listening to Radio Free Europe, who is planning to flee abroad or has access to contraband meat and razor blades and so on. These informers were themselves controlled by blackmail and fear, were fanatical supporters or were simply doing the work in exchange for favors or goods. Any individual harboring intentions to overthrow the system was thus isolated, he knew that any such talk would quickly get him sidelined from his job, evicted from his flat, sometimes declared mentally unstable and committed, and finally, if nothing else worked, disappeared.
The entire review reads like a clumsy attempt to soil Orwell's legacy, that was already, by that time, shaping to be far more significant than Asimov's own.
