Bullshit. The ideal refrigerator temperature is already close enough to freezing that any small adjustment you could make is unlikely to do any good. If this was actually a good idea then by your logic (similar to odd love for printer manufacturers) the all wise manufacturers would have already incorporated this into their “smart” fridges.

Well, basically all manufacturers have this functionality, so I don’t know what to tell you.
