I agree that these things are bad. End-users and third party repair shops should be given access to any tools and parts they need to maintain and repair a vehicle. Some designs are inherently harder to diagnose and repair though, even with access to OEM tools and parts. I reject the notion that being harder to repair is automatically bad, only when it is an intentional business decision to create vendor lock-in and not an engineering decision made to improve the quality of the product.
