To my mind, It does not make sound business sense .to upset and alienate a very large sector of your buying market .For the sake of a quick buck from miners.
the gaming and data sales are your bread and butter. keep them happy ,they will keep coming back. Upset them they have long memories.
Nvidia need to start selling directly to the public, with a presence from Asus Gigabyte etc etc .A combined shop as it were. (obviously 1 per customer

)
Nvidia should be viewing this as a PR disaster.
we need more stiff competition in the Gpu market .at the moment its a 2 horse race
