I recall reading somewhere that internet shutdowns during protests are usually counterproductive. People who were previously only voicing their frustration online or passing the time with entertainment are suddenly left with a lot of free time on their hands. While a shutdown can prevent coordination on the national scale, it can't stop people from taking to the streets and organizing spontaneously.

EDIT: Found my source: https://www.iafrikan.com/2019/05/06/shutting-down-social-med...

"Under a blackout, each successive day of protest had more violence than would typically happen as a protest unfolded with continued internet access. Meanwhile, the effects of shutdowns on peaceful demonstrations, which are usually more likely to rely on careful coordination through digital channels, were ambiguous and inconsistent. In no scenario were blackouts consistently linked to reduced levels of protest over the course of several days. Instead of curtailing protest, they seemed to encourage a tactical shift to strategies that are less orderly, more chaotic and more violent."
