Re: Bye bye Samsung
In a sense, that's pretty much every smart device. Every Windows or Apple-based computer... if it connects to the internet, it will likely have auto-updates and some form of "dial home" function.
Sure you can jail-break your smartphone and remove all the manufacturer's/reseller's apps that are otherwise untouchable while voiding the warranty in doing so - but really, you could do that with any device if you had the knowhow.
Smart Tech has long since taken control out of our hands - this is nothing new.
Block the IP address on the router so the TV can't contact Samsung servers (hope it's not a BT hub etc. as the ISP can totally communicate remotely with those too).
