What seems a "reasonable" position on designing with the (inevitable?) right for end users to effect (or, hire others to do so) their own repairs on their own kit?
[Both in and out of warranty]
Is targeting the level of support provided to "authorized service centers" likely to be sufficient? I.e., I can't imagine legislation mandating MORE support (parts, tools and technology) for users than is available for authorized service centers.
And, if there *are* no "service centers" beyond "return to factory for repair/replacement", how might that thread the needle?
