Earlier quoted context omitted.
It’s a small jump from blocking websites to blocking popular VPNs. I know two countries which block websites (Russia and Kazakhstan) and they either block or have plans to block VPNs. I don’t see centralized VPN as effective solution for that problem.
How do you block a VPN though? Do you just constantly chase after their IP addresses? I mean Netflix and similar services do try but with not much luck really.
Self hosting a vpn is still beyond the vast majority of consumers and every big player in the market has their ip ranges mapped thoroughly.
