Some people are comparing what NVIDIA has done to its hardware to crippled software. It's a bit different though. They didn't just cripple their hardware, they segmented their markets and crippled hardware and software as needed to make it almost impossible to use the same card for more than one application.
Geforce cards are crippled in software so you wouldn't want to use them for CAD work. Quadro cards are crippled in hardware and software so you wouldn't want to use them for gaming or computation, respectively. Although Teslas are also stress tested for data reliability so perhaps it's unfair to say the Quadro cards are unsuitable for computation because they're crippled intentionally.
