I can imagine how they would do with those.
Much of that equipment runs on some version of Windows. Probably CE.
Here’s the funny thing... Everything in your list that does now use firmware or software is using linux or related software. The manufacturers of these smart machines and appliances were smart enough to stay away from MS coding altogether yet we still keep abusing ourselves. Pretty bad when a wash machine, microwave oven, or dishwasher is smarter than we are. lol
A side note: if Microsoft really cleaned up and streamlined Windows the sales of X-Boxes and consoles would tank.
Think I’m joking? Look ups YouTube about games intentionally made to suck. It details how one game intentionally capped the frame rate and removed textures from the PC version because console sales were more profitable.
