If someone wants to install an advert app on their fridge (I assume in exchange for money) then fair enough.
If I buy a tv I shouldn't just have to accept that, now or in the future, the manufacturer will sell advertising on it.
But yeah I agree with you, there needs to be a way for people to get away from ads without relying on the existence of some benevolent alternate company
On a practical level you then at best have a battle to get a third party (the retailer) to give you a refund and most people faced with the option of removing and returning a huge expensive device like a fridge with no guarantee of a refund are going to just leave it.
It does need some stubborn and tenacious people to make a stand and set a president - perhaps backed by a consumer rights group but it's an uphill battle.
oh I'll fix it with a hammer, or glue a piece of cardboard on it.
I paid extra for devices without WiFi when I moved house this year.
