That's true but we have the benefit of unlimited time, having physical control, the analog hole.

As far as I know cars are a special case in much of the world (US, EU, others?). Right to repair laws laws usually give you the right to use non-OEM parts.

Aren't DMCA anti-circumvention provisions the bigger concern in the US? I think the EU has an exemption to allow reverse engineering for the purposes of interoperability and repair.
