I stopped connecting my TVs to the internet when Samsung started pushing notification ads for GameFly on a (at the time) 3k dollar first gen 4K tv - and they lied and said no they’d never do that. They’ve all lost my trust.
In addition to push notifications, they kept pushing their TV+ app to the first position of my apps selector. I kept removing it. Then I just switched off internet access. Smart TVs are dumb.
I disabled autoupdates on everything after a smart TV whose dashboard I'd laid out to suit me, auto-updated and insisted on dashboard apps that I never wanted and couldn't delete or hide. Got an Apple TV and have not touched the smart TV features since.
Wow, I didn't know it was that bad! I've never connected my tv's to the internet. I normally run a full PC behind them to access our media and for apps.
