The odds of a Chinese homed VPN provider not sharing logs with the Party asymptotically approach zero as time and user count increase.
Providing vpn services is almost illegal in china. The party doesnt ask for logs; it shuts down vpn services and punishes the providers. So the odds of vpn provider sharing logs with the government is ironically low.
Yes, offer them free VPN, what good is encryption if you're connected to a server they own/have influence over?
