Re: They aren't completely wrong
Once your device is connected to the VPN it should be insulated from local network traffic.
I don't think NordVPN is perfect but with governments and advertisers planning ever more invasive measures I'm beginning to regard the ads as a kind of public information campaign. Just like eventually all websites switched to https (okay, not all have), if everyone starts running a VPN then certain parties will have to work a little bit harder to snoop on everyone all the time.
