Real consequences from higher up... for ads on a fridge? Corporate execs only care about money. Engineers aren't going to get themselves fired every time someone asks for a feature they don't agree with. Government? We don't need more nanny laws.
What we need is for people to think for themselves. The powers that be aren't going to save you from all the bad things. Call out the bad things to educate people, and vote with your wallet.
There's a whole growing class of people that do not have the ability to vote with their wallet. Fridges, TVs etc will all be at their cheapest because they're subsidized by ads. Or worse, if you're a renter then there's a big incentive for apartments to put up smart fridges in every room both as a selling point and for ad revenue.
How would you propose to deal with apartments having every fridge be a smart one?
