I think you're misreading my comment. I find the threat real and probably already in action. My key point is that hard-banning a popular resource in a country without a DPI-like firewall is just a national security theater with no effect.

Take an example from Russia - instead of banning youtube, they just make it crawl and stutter, so fully controlled rutube/dzen/etc start to seem more viable, but it's not too bad to decide to go full VPN. Non-technical people don't even realize that it happens and write it off as some youtube-related network issues.

Of course that is an awful attack on freedom, but you can get real or get rekt.
