China’s Planning to Partially Lift Web Censorship in Hainan

Anecdote time: I once met a mainland Chinese software engineer who told me that his department pays for a VPN subscription so they can access the uncensored internet for work.
I haven't been to Hainan though so I don't know about any particular issues there.
Most big tech companies already provide internet outside of the GFW. Microsoft China did st least, I’m sure most others did as well.
China telecom (communist one, not one from Taiwan) provides "private fibre," to HK. Famously, they claim it to be a physical connection, but if you try loading anything blocked by GFW it will still be blocked. And you can't use anything other ethernet/IP or MPLS/IP on it.
Once we were buying private fibre for our office, we asked a technician the "WTF" question. He plainly asked if we want VPN, then he said that you first have to buy private fibre, then run your own VPN over it.
I believe, all big Cos have it that way. I once visited Microsoft's campus for an event. I noticed that "what is my ip" in google.com shows an IP of a noname Hongkong datacentre rental company.
