The GFW is likely sophisticated enough to make distinctions between corporate VPN connectivity using products like Cisco AnyConnect and personal use setups on AWS/DO/Azure/GC or even a home server.

One of the things I've wondered about, and I hope people more informed than me will forgive my ignorance, is whether it's possible to implement a VPN protocol that looks like ordinary HTTPS traffic. I know very little about the specific mechanics of network protocols so the very premise might be nonsensical but I would appreciate an explanation of why this might or might not be possible.
