This all applies to cryptocurrency miners too.

In fact, it might be even more relevant there, because crypto miners compete so hard on electric bill costs, they definitely have to plan on liquidating equipment when it gets old enough, even if it still works. I think a lot of miners still use regular consumer GPUs to this day because with a specialized card that has no video output, it can depreciate from $1000+ to worthless almost instantly. There just end up being no buyers.

If this was all real business and not just the authorities controlling people, Nvidia would have competition offering similar cards with video outputs for a few cents more, because that product would make more business sense. But instead, it would be super expensive to add video outputs to specialized cards, because it would "cannibalize sales" for graphics cards later (i.e. give savings to consumers)
