I know it isn’t specific to just Linux but I use Linux anyway so my question is,
Is there a way you could use a VPN without them knowing that? Or if they outlaw them is it really just game over?
If they made VPNs illegal I suppose stuff like TOR would follow except TOR is partly funded by the US state department and the US is one of my countries closest allies (one of the five eyes). So surely they wouldn’t shut down something the US funds directly… Would they?
I’ve read very very little about Gemini and other protocols like Gopher, would this be the way forward if they do this? And is that even remotely close to the security and potential anonymity you would receive from a VPN?
Not necessarily. It’s reasonably easy to keep long lists of known IP address ranges of known VPN providers and block access to these, but VPN traffic to a not well known IP address is generally impossible to distinguish from perfectly legal encrypted traffic such as a VPN connection to a corporate intranet. (There are also VPN protocols that are made deliberately hard to identify at all.)
It is distinguishable via deep-packet-inspection, China uses this
