In fact, it's really quite amazing that car manufacturers, generational artisans of the vendor lock-in have not been doing this at a far greater scale. Think of all those generic screws they could be charging $50 each for. No one buys or doesn't buy cars based on the screw heads. If they did they'd also reject cars that require thousands in probes and an annual subscription to use them, and they don't.

It's not even that they don't have their own screws made by tier 1/2s, as if you look in a car, many seemingly-ordinary screws do in fact have the brand and part number stamped in the heads - presumably for stock and quality control purposes during manufacture.
