but it's not basic functionality if it's only in 10% of devices on the market.

it seems like you're hung up on a particular feature of a device no longer existing and you have an inability to accept change. I can appreciate that.

personally, I hate vehicles with "infotainment" systems in them but they are installed in 75-80% of cars these days. nothing was better than the old mechanical radios with the big buttons that would "ca-chunk" the dial for you. the warm glow of the neon bulb inside dimly lighting the cab. don't even get me started on the entire removal of AM radios entirely.

if I were to let my preference for the radio stop me from buying newer vehicles I would be losing out on all of the important safety improvements made to cars over the last 40 years. things like air bags, seat belts, mathematically formulated crumple zones, auto-roll fuel pump sensors, etc. that's not even mentioning some of the comforts like power steering, AC/heating, EFI, rear window defrosting.

my point is, you have an option to continue using a headphone jack with an adapter, there are even options to repair any damage should any occur. I can't even look at my car radio like I want to replace it without a $4k dealer visit because it's integrated into the ignition system.

seems like a really silly hill to kill yourself on.
