IT's the same with many other things. I don;'t
suppose many people,
 buying a new car, would have the same requirement top-of-the-list as my
 father did recently. Namely that the official workshop manual had to be
 available. But it was important to us. 
I never take delivery on a car until AFTER I have a copy of the FSM
(Factory Service Manual).
I don't often have that option with computers, but in 1981, I spent a lot
of time in the PC Tech Ref before I turned on the 5150.
But, I have driven a lot of cars and used a lot of computers that I don't
have ownership and control of.   Sucks to work for others.
