Nvidia wanted to make more money selling GPUs for mining, so they came up with the LHR version.
Nvidia didn't make money from LHR. They made money but not from LHR. LHR was mostly a marketing gimmick
to please gamers by pissing off miners during a period of high demand and short supply. The side effect is it made
AMD GPUs more attractive to miners. AMD made money from LHR.
Nvidia used LHR restrictions to sell limited warranty versions of "mining edition" graphics cards to miners. There were no LHR restrictions also for the A0000 series. Mining edition video cards are very difficult to sell on the secondary market, so miners preferred to buy regular video cards with a 3-year warranty.
