Your TV is taking snapshots of everything you watch.
You sit down to relax, put on your favorite show, and settle in for a night of binge-watching. But while you’re watching your TV… your TV is watching you.
Smart TVs take constant snapshots of everything you watch. Sometimes hundreds of snapshots a second.
You probably can use your tv without it using you, or probably not.
I, too, use pihole. But it does not prevent your data from leaking 100% and never will.
And it’s easily circumvented by using other DNS servers or even by connecting to hardcoded IPs. I dont know specifically about TVs, but some manufacturers do that.
The only way to make sure that TV can never spy is to never connect it to the internet.
