Because Intel isn’t the company you’re buying hardware from. Apple is.
When the Volkswagen scandal happened, you didn’t sue Bosch, who made the software. You sued VW, who sold you the car.
I bought an Intel CPU from a computer shop, I should sue myself for my decision to buy it? The shop for selling it to me? The distributor the shop bought it from? Are any of these entities responsible for the defective CPU? Or would that be Intel?
In law, those who do wrong are the ones held responsible. Intel’s lawyers can’t just tell the judge, “well, sure, our client designed and made defective CPUs, but Apple bought them so it’s actually their fault.” Apple played no role in Intel’s designing, manufacturing and selling of defective chips to millions of Intel’s customers (of which Apple is only one).
You present a flawed analogy. VW was sued because they were the responsible party. It was they who decided to cheat on the emissions tests, not Bosch. VW pleaded guilty to fraud and paid $20 billion in fines and penalties because VW executives made the decision to criminally defraud their customers.
In fact, Bosch was also complicit, as VW didn’t know how to program the software to recognize emissions testing and (only) activate the emissions controls properly when this compliance testing was detected. Bosch knew, or should have known, why VW asked them to make the software operate as it did.
So your analogy falls apart, since Bosch did have a role in VW’s deliberate and criminal fraud, and was therefore held accountable. Bosch paid hundreds of millions of dollars in the US in a legal settlement for writing that cheat software, albeit at VW’s request.
