I mean, do you expect a blender to come with instructions on how to replace the engine?

> I do not believe that it has the right to not document any feature of the device that is relevant for its usage.

This is an extremely broad requirement to place on any and all manufacturers. I agree companies shouldn't intentionally restrict what you can do with your stuff, but on the other hand, if you're trying to rebuild your lawn mower into a motorbike, you can't really be mad that the company didn't provide you with a specification the exact dimensions of the exhaust, can you?
