At least in the US we don't generally turn off communications infrastructure just as a response to criticism or political unrest. Or if it does happen, the government is exceptionally good at preventing that fact from surfacing.

Nah US is too advanced for that, they would rather intercept those communications and send UAV/SWAT teams to directly handle them with accuracy.

Most recent protests in the US, until 2020, have been fairly soft and lacking the vigor behind movements like the Arab Spring.

If we the people become enough of a threat, you can bet there are strategies in place to disrupt our communication infrastructure.
