Being hooked up to a router does not mean it's not airgapped. People hear router and think internet but a router is a networking tool. Think not that long ago to LAN parties, there was no internet for that. People hear router and think Wi-Fi router. But even WiFi routers don't have to be internet connected. It's just an accepted modern term.

I would love for a non-partisan person to look into their IT, again,Rob Graham knows his ****. Cotton isn't a fool, but he's paid to get a result he'll get it. I'm not a fool either.
Dr. Shiva is a quack. He's smart don't get me wrong, but his claim to fame is inventing email, he didn't. And a lot of people in the IT world hate him because he's a pompous blowhard. And unlike others doesn't seem to stay on top of things and now instead seems mainly interested in alternative medicine and conspiracy theories.
