Except it isn't. I guess it's not fashionable to talk about old cars anymore, back in the day cars were "simpler" i.e. fewer specialized components, less computer more mechanical component.
Whether the cars were better or worse, it meant a lot of independent and home grown car mechanics. We still have autoshops, but fewer, and its also much more difficult to source parts, except by relying on cheap knockoff parts from China. We barely have a manufacturing base at all anymore.
Right now, IBM computers are pretty much king. It wasn't always that way and if Apple took over you'd have much the same issue. It's the same set of market forces, I'd argue this isn't an analogy at all.
