I’m taking part in this discussion from inside China. I teach 16 year olds who have Astrill subscriptions (It’s a VPN). The point of the GFW isn’t to stop information getting in or out. It’s to maintain control over what gets discussed and to ensure that all Chinese language cultural interchange of any importance is controlled by the CPC.

Yea you are probably right. But it makes it so that the CCP can’t actively control the ISP directly. Perhaps people will hack together ground terminals or something? Where there is a will, there is a way. In any event, just standing up to China and telling them that we won’t block out service to those who can access it is better than nothing.
