There was/is a German startup called “manualOne” which offered manuals as well, and I think the idea was to establish a connection between the customer and seller of devices (like a fridge or whatever), where the customer buys the fridge in an electronics store. Normally the seller would be “blind” as it does not know its customers. And offering manuals and whatnot would help to establish the b2c relationship.
