I think a large part of it is the tech-illiteracy of world leaders. I'd wager that a lot of the folks implementing these policies don't know the difference between a DNS server and a VPN. They think DNS=VPN, so all the hackers are using cloudflare to get around restrictions. In general, most folks who use the internet don't know how it works and they don't want to know.
