Bullshit.
This is a conscious business decision to not accomodate.
Wanna know how I know? (Besides experience in tech)
Sewing machines.
Millions of ladies with sewing machines out there, and harried husbands/partners/neighborhood mechanics/machinists out there that fix the bloody things. Yet, as a fixer thereof, you'll find the older machines are jealously guarded and highly sought after for reliability, stability through heavy loads, and servicibility.
And yet... All you have is plastic pieces of crap that warp and miss stitches under load, increasing usage of integrated circuit boards and plastic gearing.
A corporation will not optimize for the utility to end user and QoSL (Quality of Service Life). They will optimize for future sales and cheaper production. Literally converging on the worst product people will still pay for.
Stop making platitudes that "Oh the economy would accommodate you if only there were more of you!"
It is grade A, concentrated, unadulterated, Bull. Fucking. Shit. The business world will wring every last cent they can out of the buyer, while spending the absolute minimum required to "solve" the problem they set out to fix, and arguably, don't.
I am Quality Inspector number effing 7. I get into knock down, drag out brawls with management on the crap they expect me to put my seal of approval on for the sake of being there to be sneered at by the by the end user.
Enough is e-frigging-nough.
Since you brought up automotive. Same damn thing. Can you get cars with open-source, well documented software running on the ECM and BCM? No. Is CANBUS free and open? Nope. Are engine compartments built for anything else than the ability to be assembled by automaton? Nope.
Farm tractors and Ag equipment. Same bloody thing. This is all according to plan, because it's the default, and capital decides what the most profitable default is going to be.
