I did something like that with my robot vacuum. I opened it up and ripped the soldered-on wifi card. Now I can’t control it from my phone, but it can’t phone home to Shark either. I was willing to risk it for a $400 robot vacuum, which I also happened to have a second defective one to practice on thanks to their return policy. I’m not sure if I’d attempt this on an electronics behemoth worth several thousands of dollars that I can’t afford to lose.
“Friendly” is not the name I would use for my average counterstrike team.
