I agree, repairability is more important than manufacturers maintaining an iron grip. And that iron grip almost certainly has holes too, which can be exploited by malicious parties...whether or not owners have access. The question isn't whether 'bad guys' may get access... it's whether the 'good guys' will also have access.
Owners should not need to resort to holes to gain freedom to carry out their own maintenance and repairs and hardware replacements. Repairability is critical for keeping equipment functional, at reasonable prices, over the long term. I'd say it is also more important on large, expensive, long life hardware than on small electronics, though in both cases repairability helps reduce waste. On security: there are ways to guarantee local physical presence before software/firmware is changed. A physical write-protect switch or a jumper that must be moved is one of them. Some computers have required this kind of thing before BIOS updates could be made.
