My take is that most people use VK instead of Facebook and Twitter isn't used much either. Sure, some people use it, but it's nowhere near the popularity of Telegram or Instagram.

Some friends, who lurk on Facebook more, do periodically share this or that post that seems to be bashing Russia, so no wonder they blocked Facebook. Same for Twitter. I think people might get more hurt by a ban of Instagram.

Another point is that people who care enough about free speech, democracy, etc. are more likely to be aware of and use VPN services, so they might still be able to access the content, but people who don't use VPN are unlikely to install it just to check some viral anti-regime post on Facebook, so maybe this is a move to prevent future growth of the audience reading news on Facebook.

Of course, take this all with a grain of salt, as I hardly use Facebook or Twitter, just Messenger sometimes. I'm mostly extrapolating from the usage by my friends and family.
