Maybe Nintendo/Sony uses Nvidia cards on their developer machines? I imagine FreeBSD drivers aren't simply altruism on their part.
On the other hand, stagnation on other fronts:
- Nouveau (tried recently) is basically unusable on Ubuntu. As in the mouse/keyboard locks every 6 seconds.
- Proprietary drivers won't work with wayland
And since their stuff isn't open, the community can't do much to push Nouveau forward.
