1957 Ford Edsel
Do 1957 Edsel's make up a significant portion of the current vehicle fleet? Or even of Ford's currently used fleet?
Honda and Toyota(IIRC) had a fault in their airbags in 2015 or thereabouts. They recalled vehicles for a free replacement all the way back to 2000, maybe earlier, that were affected. This is quite comparable, especially given the amount of re-write that went into XP SP3 making it closer to a new release than a service pack. And replacing code in software is orders of magnitude cheaper than replacing parts in a car, in software you only have to put the code on your update servers (which exist already) and let the update software do its job, whereas with a car you have to pay a suitably qualified mechanic (some recall work can be done by apprentices with a little training, some need a specialist) to replace the parts, which can cost several $hundred per car
There's what, maybe a couple of hundred 1957 Edsels left in the world, of which a small handful are used on a regular basis? Whereas XP makes up what, 5% of computers still in use? (actually back of my mind I think it's closer to 15% but ICBW). That breaks your analogy somewhat.
