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.
Do you want to talk to my 70 year old father about how he should come up with solutions to ads on his fridge? Yes he can grab a garbage bag and some tape, we can all probably agree that the day stuff like that is commonplace we have very, VERY evidently failed as a society when it comes to dealing with this specific issue.
