For sure, taking control away from the users is terrible and scummy, but I think it’s an entirely different issue, covered by “right to repair”. A very small amount of people had the know how and the confidence to perform the repairs themselves even before this anti consumer practices became so widespread, so I don’t think it’s a huge factor in decrease of skill. I would say a much bigger factor is the fact that technology has become exponentially more complex. You can’t just open up a radio and replace a vacuum tube, everything is a microchip now, and the soldering iron isn’t gonna help much there. I guess eventually we will reach technology complexity and abstraction of such a level that no single person can hold the knowledge to “fix” it on their own.
