In a way. Basically yes any totalitarian regime will want to create a system where the people in charge have total control over everyone and everything. But my point is that Stalin was able to exert control over all parts of the Soviet Union without the internet, Facebook, WhatsApp, backdoored E2E messaging systems, email and email spying, parallel construction, etc.

The comment I was replying to is not wrong exactly but the better way to phrase that is that any unrelated but centralized system can and probably will be co-opted by a totalitarian regime and in the long run only helps the oppressor and not the oppressed.
