What would happen if the western tech giants decide to shutdown every service in russia? No AWS, no GCP, no peering, etc. I am pretty sure, that most companies in russia rely on western infrastructur in some way. Also it would be pretty hard for russia to keep spreading fake news. I guess that Putin would loose his remaining following if the smartphones of the population became useless.
