The same argument can be applied to the hardware. We have a lot of different hardware, it's all different, and every pice of hardware needs its own driver. In practice, drivers are created by hardware vendors and often they are open source. Of course, production processes are more complicated than this, but there's a degree of decoupling of the processor together with its architecture from the production process.
