IME consumer electronics have gotten a lot better about this, but appliances and other things outside the tech sphere are still awful. My portable AC unit has a bright-as-hell seven-segment display for the temperature which shows "--" even when it's turned off!
This might just be amateur EEs doing their thing in an organization that doesn't constrain these aspects of the product. Data sheet says If(cont)=20 mA? Okay, 20 mA it is.
