The more impactful and subtle part of this discussion includes what constraints, rights and responsibilities does this place on manufacture?

If we decide you have an inalienable right to repair the phone I made for you, does that mean I have to facilitate it? Does it mean I can't put technical barriers in place to make it harder for you? Do I have to offer you any sort of support & warrantee if you have modified it?

Can I refuse to offer you a sale on the object, and just offer a lease? Etc. etc.
