The dictatorship was enabled by violation of people's privacy, that's why it managed to survived so long.
Privacy isn't an optional feature you can "chose" to have or even have much control over, it is a basic right that is either violated or honored by those in power.
What enabled the dictatorship was punishing people for perceived disloyalty and shooting people who tried to leave. Privacy was, at best, a weak defence against that, and arguably much of the Stasi's raison d'etre was to convince citizens their concerns about the government ought to stay private.
Better a Germany where people feel safe to share far more on social media than the Stasi could ever have collected, because they don't expect to suffer consequences from doing so.
