Your 45 year old rotary telephone could also have encrypted the numbers you're dialing. Buying user-hostile devices is what leads to user-hostile behaviour.

Apps needing to opt into CA certificates are an annoyance for sure but in 45 years the API those apps are talking to won't be running anyway. You'll still be able to buy WiFi adaptors for whatever tech we'll use by then to physically hook up your current devices, but the network itself won't work unless you set up a server for yourself.

Your converter box is similarly difficult, an old "speaker hooked up to a wire" protocol has been converted into a fully fledged Internet appliance. The POTS services that the phone wants to connect to are no longer there, you need to spoof them; the same will be true for the smart crapware we buy today.
