One could argue this is the exact same thing: protecting their long-time customers from a small number of big customers (datacenters) that can afford to dramatically out-price their gamer customers temporarily, but might disappear (if they develop their own hardware?) not too long from now.
Isn't that kind of the point? If consumers and enterprises were competing for the same product, we would probably see a similar situation as we are with consumers and miners.
We would also see higher prices for consumers, since Nvidia would need to crank up higher profit margin a bit on their RTX cards to make the same average profit per chip sold without their high margin Quadro cards going to enterprise.
