> Keeping things up to date and holding critical infrastructure to higher standards than consumer tech is not a bad idea.

This is a great theory, but practice (over centuries now if not millennia) tells us that critical infrastructure is rarely properly maintained. "If it ain't broke, don't fix it" is the motto of governments and large organizations everywhere when it comes to proper maintenance. As opposed to improper (keep the existing thing running) maintenance, proper maintenance requires being proactive and is expensive, often requiring partial or full replacements of systems while also keeping the old system running until a hand-off time. In order to get a government or corporation to be proactive, they have to see a problem.

No problem, no worry. That it can be hacked is not a problem from their perspective. That it has been hacked might be a problem to them, but only if their constituents find out. More likely, they'll make it the poor engineer's problem, the engineer who had no budget and no staff to address it beforehand.

When it's time to cut costs, proper maintenance is one of the first places organizations look to because it's not a present problem. Then it becomes normal to not do the work, from an organizational perspective, and all those engineers and technicians are just a bunch of Cassandras.
