You are right, the model is great for some people in some cases. However, its a model where companies use software to lock you out of being able to use your hardware. This is becoming extremely widespread. Consider also the farmers having to deal with the John Deere tractor licenses and being unable to maintain their own equipment (or Apple preventing you from being able to upgrade or repair your macs/iphones).
The problem is that as the practice scales, people end up with no real property rights, and are just ensnared in a hundred terms of service agreements that they literally cannot escape while living a normal life.
Lots of potentially dangerous things are harmless or even pleasant on a small scale.
