They were the first to provide actually usable GPU drivers on Linux. But then the kernel guys became upset because they couldn't see the insides of the drivers. IIRC they started the holy crusade when they introduced the tainted flag in the kernel and made it policy to ignore all bug reports from kernels with that flag set. That was designed specifically to make nVidia look like a bad actor. There have been a number of similar sleights against them from various developers and the company took the beating and has so far worked stoically around all of these hurdles that were erected.
I am not saying that they are saints, but singling out the vendor of the objectively best GPU hardware and software package in the market like that does not feel right, either. There are tons of users out there that have practically no alternative to that hardware and they are being screwed over. And they are one of the few markets in which Linux actually has a dominant share in.
Long story short: I believe that kind of ideology first thinking might do the Linux software stack in in the long run.
