Russian Government itself is working hard to isolate their segment of internet so they can control it and firewall it Chinese style to push their propaganda unrestricted. So willfully cutting it off for them is essentially helping the enemy.

There used to be Radio Svoboda to counter Soviet propaganda. Nowadays West need to be working hard to ensure there is internet in Russia and news and communications are available, so regular people cans see non-government news sources and dissidents can securely coordinate. I don't understand why it's so hard to comprehend.
