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).
