It would be cutting out a massive chunk of Framework's potential customers to not even offer Nvidia GPUs.
I don't like Nvidia at all, they're a scummy company. But just offering their products as an option is not "openly hostile and offensive" to Linux users. That's a bizarre take.
Until modern times, Intel was the largest GPU manufacture, unless you include phones, then it was Qualcomm.
Now it's AMD, between computers, consoles, and the datacenter.
DGPUs for the desktop aren't really all that relevant for either AMD and NV's bottom lines, they're not major sellers. Switch sales also aren't enough to compete with combined Xbox/Playstation sales.
A lot of claims of NV's superiority is just marketing smoke and mirrors.
Yes, technically they make many by volume. But they are very limited integrated GPUs. Fine for basic encoding/decoding operations, not really practical outside of browsing and e-mail checking.
AMD has been doing fantastic in the mobile and console space, I admit that. Their products are decently energy efficient and powerful for what they are. But they're struggling to keep up with the leading edge and their market share is tanking because of it.
Nvidia has a 92% market share in the discrete GPU market, with AMD holding 8% and Intel 0%.
That is not a healthy spread.
Nobody cares if Nvidia sells lots of DGPUs if ye average Fortune 500 company isn't deploying devices with DGPUs in them and the app they're paying a million dollars a year for suddenly breaks on Intel.
People need to remember that there is an entire world of computing outside of datacenters and high performance desktops.
