I don't think this is a useful stance to take for more or less any reason (any reason you can point to will have a different underlying issue). Cars functionally have to have microprocessors, if nothing else but to control emissions, and that's a good thing. I don't want society to smell of exhaust, so that's an obvious and gigantic benefit. There are many other good reasons to have them, like rear cameras, tire pressure sensors, infotainment, the lot.

There are downsides, but many boil down to 'manufacturers are knobheads' (data collection, pushing subscriptions) and lessened control (tuning computers can be easier than tuning mechanics, you just aren't given control, so this to is arguably a case of 'manufacturers are knobheads', or sometimes liability issues).
