Yeah, even cheap microcontrollers nowadays with support for clock functionality have an ultra low power mode were the only thing running is the clock crystal and the clock functionality which uses so little power that it can run for years from such a button battery.
The thing could do the same as my stupidly cheap alarm clock that has some batteries as power backup and just keep on counting time without displaying whilst mains power is down so that when mains power comes back up it still has the right time.
The extra $1 for the hardware needed for it is hardly going to matter next to the overal cost of anything but a stupidly cheap microwave.



Also later in time when one is making a choice for a kind of product one doesn’t usually buy, one might have forgotten their dislike for a brand due to their excessive use of advertising and yet their subconscious is still giving them a feeling of familiarity when they see that brand’s name on a product which makes it more likely that they’ll chose it over other options that don’t feel as familiar.
Most advertising nowadays is meant to affect subconscious impulses which will do their thing with no cognitive effort, whilst the position the OP holds (and which I myself try to) is conscious and requires cognitive effort to maintain.
