Earlier quoted context omitted.
How would you organize protest with the government controlling communication? You have far more trust in the good will of those in power than I do.
Protests happened before the Internet. Before telephones, even. Neither are a requirement for people to communicate and organize.
That would not be the case in this instance. You (the protestors) would be back to runners, unencrypted radio/code. They'd still have the modern comm suite.
It doesn't make things impossible for protestors, but it greatly shifts things in the government's favor for containment and ability to sustain itself against a now unconsenting populace. Always remember asymmetry will be employed as early and often as possible.
