"Kids, that ugly, old refrigerator without a screen sitting in the garage is worth a lot of money and is your inheritance."

Aftermarket in old fridge doors. Unless they put DRM in to stop the compressor from running I'm not sure how they'd prevent it.

People like nice clean looking kitchens. A kitchen with a display flashing crap does not fit into that.

I'm sure some percentage of fridges will have displays flashing shitty adverts all day long, but there will be a large number of fridges that are just decent looking boxes with stainless, black, or white doors.

With TVs I'm afraid we're screwed though. Adding a brain and wifi to a TV is super cheap now and manufacturers have already figured out how to monetize having a smart TV in your house even without advertising.

My Samsung TV has built in ads, which I HATE. I want a dumb TV. Apps built into TVs generally suck because to keep the BOM cost down they put in the cheapest SoC that will function, leaving the apps sluggish, jerky, and frequently cut down in features. On my previous LG TV I couldn't turn off motion smoothing on the bui8lt in video streaming apps. With the Samsung TV I just don't connect it to the network because there are ads that you cannot disable.
