Answer 1

Nobody can practically forbid or allow VPNs since there is no real way to tell whether a connection is a VPN or not.

For example
My home (China) -> VPN (US) -> US Hulu

There is no way US Hulu would know VPN server is forwarding data to my house in China.

The only way US Hulu can find VPN addresses is to have their employees sign up for VPN services and connect to Hulu servers exposing the VPN IP and adding it to a ban list.
