With all due respect if you buy a refrigerator with a giant screen slapped on the front of it, what exactly is the long-term expectation? People who want that level of tech in an appliance generally know the game, connected displays come with bloatware, data mining, and yes… ads.
I get being annoyed that Samsung turned it on by default, but acting shocked that a 32-inch Wi-Fi billboard in your kitchen might eventually be used as, well, a billboard feels a little naïve. This is the trade-off we keep making with smart everything convenience up front, monetization later.
