Yeah, I think there's some interesting related trends involved to. I still feel inclined with every new appliance to read the full manual, but I know not everyone has that kind of time or attention, especially if "I can just watch a YouTube video of it" is an option.
On the other side, you see appliance companies responding to that and shrinking their manuals of useful content because they assume you might just go watch YouTube videos instead. Some of the better ones might even include a QR code or 3 to officially produced YouTube videos, though so far that still seems rare.
Even in this video is the surprise reveal that something that used to be very common in manuals, full cycle timing diagrams, was "hidden" on a data sheet attached inside the door itself. Admittedly, it's great in that case to know that should that model be taken to repair that a repair shop might find that data sheet easily without having to search manufacturers' websites, but on the other hand some of those diagrams would be quite useful to me if I was the user of that machine.
