While Ukraines calls for curbs on online sources to Russian government propaganda have generated wide sympathy and some action by key American companies, the effort to cut off Russia from the Internet overall has generated significant backlash from digital rights advocates. They argue that isolating Russians from online services and especially social media deprives them of access to information about the war in Ukraine, leaving government-controlled media as the only source of news.

I have mixed feeling about this strategy, I believe it could hurt protest and opposition against Putin's war.
