Presumably a reference to (or a subset of) "security through obscurity".
Best rationalization for old-tech-hoarding I have seen in a long time.
Probably worth a longer cybersecurity post or a few. Like how to source (obtain), repair, maintain, and integrate with (or isolate from!) modern systems, or somewhere in between like local-only secure data transfers between such systems, perhaps gapped a la sneakernet.
