The "problem" is noone cares and certainly doesn't want to pay for the costs, especially the end users. That EOL equipment still works, there are next to no practical problems for the vast vast vast vast vast vast vast majority of people. You cannot convince them that this is a problem (for them) worth spending (their) money on.

Even during the best of times people simply do not give a fuck about privacy.

Honestly, if there is a problem at all I would say it's the uselessness of the Intelligence Community when actually posed with an espionage attack on our national security. FBI and CISA's response has been "Can't do; don't use." and I haven't heard a peep from the CIA or NSA.
