Most of modern tech isn't designed with repairability in mind because often the total cost of replacing (in the developed world) ends up being lower than repairing. It's very unfortunate and wasteful, but that's just what the tech industry has moved to, and these modern cars are no different. Companies also prefer this because that way, they can sell you another product instead of supporting an existing one.
We're just unfortunately stuck because replacing a part isn't as trivial here and usually is expensive but we also lack the technical expertise required to repair them.
Yes, there definitely are people who prefer to have simplicity and repairability as well and that divide is all over the world.
But we have always had cars infused with tech that could break down as soon as you even breathe on them and then have no one to repair or service them without spending a small fortune. Look at the german brands for example. All the Chinese are doing is giving you a similar experience for far cheaper.
Also, for people who prefer reliability, the safer and simpler options still exist in the market. You have Toyota, Honda and Suzuki for example.
