These kinds of revolutions are often, for the incumbent government, the death of a thousand papercuts.
No one thing really seems to motivate everybody to stop complying. They just get more and more fed up, little by little. Intrusive police are one cut, ineffectual bureaucracy another, high taxes might be another, messing with email one more, etc. so that you can never really say for sure which mistake was the downfall of the state.
Specifically screwing directly with people who are already disgruntled and already making movements of protest, however, has the potential to be a very big papercut, though.
