First, User space != users. Second, he's berating that kernel maintainer saying that even if user space does something absurd, the kernel accommodates such absurdity. The user space program being bad, doesn't give the kernel any reason to break it intentionally.

Actually, these are pretty bad examples. Both of those fits of anger ultimately come down to caring about the users, but especially the NVIDIA one. I eventually gave up and switched to AMD graphics, but from 2004 to at least around 2016 I was running NVIDIA graphics on Linux and their increasing apathy towards Linux desktop users and Linux in general was clear. It just now is getting better, long after Torvalds complained about it, and even then it'll be a long time before things are stable and in good shape for most users. (e.g. only RTX 20xx cards are covered by the new "open" drivers, for example.)

Did you actually read/watch/listen to any of these?

These are examples of a committed champion and friend of users defending their interests.
