The problem is that non-repairability has an economic logic. Essentially, you make a machine with a rather predictable lifetime. It is the equivalent of renting the machine out. You're can then offer support for that time period. If the time period is long enough, customers will want to upgrade the whole caboodle at the end. Everyone's happy. And with the focus on a single product, you have the scale to pour resources into product design. This approach will attract demanding customers - like the hn crowd - who will put demands on support as they customize and tinker. Then, if they extend it a lot, they'll likely buy from other suppliers who free-ride off your development work. So you lose repeat custom. Tl;dr: there's a reason why modern cars don't have easily accessible engines, and do come with fixed-term support packages. Bundling works. It may even be best for the consumer.
