In my eyes, iFixit is doing the customers and the environment a disservice with mixing the actual repairability with the question of "DRM" in parts.

Yes, limitations of self-repair should be clearly pointed out and discussed critically. But on the other side, if the phone becomes easier to repair for Apple-certified shops and Apple shops themselves, this is very important. Because repairs do get cheaper for the customer and repairing phones is good for the environment. Progress there should not be conflated with the DRM issue. They should rather introduce a second score, if they want to score on that.
