NV saw the profits it made from the shortages of the last mining boom, and determined that it was better to make a much higher profit even at the cost of shipping fewer units. They went full bore on the 'costs and tdp don't matter'. They saw that people were willing to pay any price for cards that were 5% faster at a higher power draw.

Only, the mining boom is over, there are a mountain of 3000 series cards floating around out there, and NV is sweating. The flood of used mining cards is going to make this the first good time to buy a GPU in years and no amount of shenanigans with 4000 series cards is going to change that math.
