I have zero sympathy for Nvidia and haven't used their hardware for about two decades, but amdgpu is the sole reason I stick to linux-lts kernels. They introduce massive regressions into every mainline release, even if I delay kernel updates by several minor versions (to something like x.y.5), it's still often buggy and crashy.

They do care about but reports, and their drivers — when given time to stabilize — provide the best experience across all operating systems (easy updates, etc), but IME mainline kernels should be treated as alpha-to-beta material.
