Because it can be trivially duplicated, this is minimally capable engineering. Yet automakers everywhere lack even this level of competence. By reasonable measure, they are poor at their job.
My previous one lasted more than 20 years, from when my parents bought it for me when I went to study until some time in my 40s. It was still functional, but its dial had become loose and it didn't look that great anymore.
The one I bought after that follows the new pattern, it has buttons up the wazoo and who even knows what they do? To be honest I just need one power setting with a time and maybe a defrost option?
I stab a potato and cover it in butter and salt, put it on a plate, press "potato" and it's cooked just perfect every time. Doesn't matter if it's big or small, it's just right.
When I have a plate of leftovers I just press reheat and it's perfect pretty much every time. Could be pork chops and Mac and cheese, could be a spaghetti with marinara sauce, could be whatever. Toss it in, lightly cover, press reheat, and it's good.
When I want to quickly thaw out some ground beef or ground sausage, I just toss it in, press defrost, put in a weight to a tenth of a pound, and it's defrosted without really being cooked yet.
Back when I microwaved popcorn, just pressing the popcorn button was spot on. Didn't matter what the bag size was, didn't matter the brand, the bag was always pretty much fully popped and not burned.
Despite being the same age it's still in excellent working order while yours with the dials fell apart.
