It is in the interests of the user to do away with the costs and complexities of making something maintainable and the consequent obligation to do maintenance.
This only doesn't work well because once something reaches a reasonable 'end of life', there often is no identical or equal replacement. This generates in the user a wish that they could maintain their old device to prolong its use, to avoid having to choose and learn a new and different device which may not even have any improvements.
There is no reason an item can't be user friendly, reliable, and need no maintenance.
The majority of people don't even maintain their bodies, which are priceless and irreplacable - it does not make sense to say capitalism is failing because it's not meeting people's interest in doing maintenance, when people don't show any interest in doing maintenance (outside of a small subset who care about maintaining certain specific highly prized or expensive and necessary items).
Without intervention, the artefacts of civilization would literally crumble within decades. With proper maintenance, a building could last for centuries, a car for decades, a computer or phone I would hope for at least 5 years.
Our throwaway culture is threatening our existence via environmental degradation. We're in the middle of a mass extinction, and climate change could literally end life on Earth. We need to consider the long term sustainability of our economy, way of life, and civilization.
The computer I used before that was from 2006. Which is now in use by my sister.
Both of them have been unmaintained (except for automated updates of Kubuntu) since first installation.
The same I expect from phones. And from washing machines.
My family’s microwave has been bought and unmaintained since 30 years ago, and that’s what devices should provide:
A literal lifetime of working without maintenance.
OTOH, I always maintain it by taking it into the shop and having them do what they do.
The only issue I'm having now is the A/C would sometimes go out last summer, but I'll be getting that looked at as we get into the summer months.
I expect this vehicle to be running just as well at 240k miles. I've already got over 10 years in it and I don't expect another 10 years to be outlandish.
That's lasting power, but I don't maintain the vehicle myself, I pay others to do it for me.
