I've downloaded and installed NordVPN on Ubuntu and am a bit incredulous at its operation.
After I downloaded its .deb file and installed it, apparently it can be activated with the command
nordvpn connect, and I'm expected to believe that this command encrypts and reroutes all packets from my machine to go to their servers first.
This seems like a pretty big operation that should require communication with the operating system. If I had multiple users on my system, they are all suddenly having their applications redirect to NordVPN's servers. Why doesn't it require sudo?
I should note that other VPNs with command line interfaces seem to work this way as well (ExpressVPN).
