"Tech Company: At long last, we have created the Torment Nexus from classic sci-fi novel Don't Create The Torment Nexus"

I think Black Mirror is neither a deterrent nor a guide, and 1984 is more on the "deterrent" side. A ton of policy debates tend to get shut down almost immediately whenever someone says "this is 1984". Our level of surveillance is way, way, way below what our technology allows (yet still above what is desirable in a free society), and I suspect 1984's existence is a major reason for that fact.

It depends on your country of residence. In certain authoritarian countries, 1984 was definitely used as a guide on what to implement in terms of facial recognition, scanning of device data, always on recording in public, etc.
