It's one thing to be a jerk to Nvidia, which seems justifiable. It's another thing to be a jerk to Nvidia users who may simply be unaware of the harm their GPU vendor has done.

I think it's perfectly understandable (and perhaps even useful) to lose your composure when you have a bunch of users who act entitled and complain about your (free) software being "broken", when it's the fault of their GPU vendor, who makes a ton of money off their user base.

It seems like a big problem for the Wayland ecosystem that support for a large category of video cards depends on one volunteer.

>support for a large category of video cards depends on one volunteer.

How did you come to that conclusion? SirCmpwn doesn't maintain Wayland Nvidia support, just the Sway Compositor. If you want a Wayland compositor that supports Nvidia-proprietary, you can use GNOME.

The last time Sway came up as a topic at HN there was a conversation about whether a particular terminal manager was compatible with it yet. It seems to me that if the applications you use can have compatibility issues with the compositor you use, if you want to use an application your choice of compositors will be necessarily restrained to those that are compatible. And if compositors can be compatible or incompatible with particular hardware, that means that it's possible to have an application you want to use that is only compatible with compositors that are incompatible with your hardware.

What am I missing?

It doesn't. Support for that large category of video cards depends on the manufacturer of those video cards.

Is he being a jerk because he doesn't want to do a bunch of unpaid work? If your car manufacturer doesn't want to fix your broken car, am I a jerk for not doing it for them?

No, but you are a jerk if you tell people who want to use your software to "fuck off" or buy a different car.

Did he tell the people that? Or Nvidia? I must have missed it, if it was the former.
