I moved into an apartment with a high-end washer/dryer combo and was displeased to find out that it comes with a 30-second jingle every time it does anything that you can't turn off. Apparently it's ubiquitous now as I've whined about this to any visitor who hears it and they tell me theirs does it too.

It seems like a show of power. "You're going to give us $4000 for some appliances and we're going to make you listen to a 30-second MIDI track each time your load is done, and there's nothing you can do about it :)"

I've pulled open microwaves and removed the buzzer. My flatmate thought I was nuts at the time but as a person often up late reheating things it's a considerate thing to do, there's no need for a device where you can't turn off the sound. Even worse when it continues making noises every 30 seconds afterwards until you open the door. RIP anyone who likes to cook then cool.

Microwaves are already loud appliances, I can hear it running from the next room. Meanwhile you'll be hard-pressed to find a toaster that beeps.

I have recent (current model), reasonably high-end Samsung washer and dryer, and while they have a jingle like that, it's fairly easy to turn off (it's a secondary function on the control for the dryer, but even there is clearly marked so not obscure.)

I enjoy my LGs jingle. It is nice and distinct from the generic beep everything else gives.

And there are plenty of other fans. :)

mostly these are configurable to replace with a beep. Lot's of people like the melodies it seems.
