@falcon @dalias Maintaining legacy systems can become impossible even when you want to. Case in point, it has become literally impossible to maintain analog or even many older (actually more secure, dedicated) digital communications links. The carriers (e.g. AT&T) simply will not provide them, or in some cases even fix them when they fail (this goes far, far beyond landlines, which I've discussed many times and will probably be discussing again Monday on my national radio tech segment). And the reason the carriers no longer will provide those circuits and systems is that regulators have permitted them to do so -- a situation that will only accelerate now under the new MAGA FCC chairman. And the regulators have been largely bought and owned by politicians from both parties over the many years. Firms can't use what they can't obtain!
