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.
No, this does not need legislation. If you don't wants ads on your refrigerator, how about not buying a refrigerator with a screen built in, it's not necessary.
That said, I doubt these companies would sue because of the risk of setting a precedent in favor of the consumer. Scary legal letters (e.g. cease & desist letters) perhaps. But given enough customers, at least one will have the resources to hire a good lawyer and fight it all the way to court.
