No thank you.
Some Miele washers still come with basic circuit diagrams in my experience, but yeah that’s far from the norm.
To be fair, compliance with that in those cases might be easier. In my experience most washing machines, for example, have programming headers near their main microcontrollers, and you absolutely could write your own firmware for them. Occasionally they’ve been locked down and require an exploit to reprogram (looking at you, Nordic!) but in many cases putting your own code on is as simple as looking up the part number and buying an appropriate JTAG cable. Working out how it’s all connected inside is slightly harder, however.
Works on contingency? No, money down!
I have a UDR and it’s pretty great. I have had one unknown failure once, which needed a physical reboot. And that’s been in two or so years.
