I wonder if it's a similar thing about the supposed benefits companies thought they were going to get about limiting the customers "right" to repair their products.
On one hand, the benefit look "obvious", yet when you take into consideration the second-hand effects (like bad publicity, people getting frustrated by the inability to repair and getting a cheaper alternative) my guess is the costs were bigger than the benefits.
