> I don't get the "everything needs to support dark theme" thing either tbh

I started my career when screens were black with text displayed using green/white/amber phosphor and was used to that. I never liked the bright white UIs when GUI based OS/front ends took over (before themes became a thing).

I find the wall of bright white with black/dark text tiring to look at. Collaborating with colleagues doing screen sharing where they don't use dark themes is really jarring.

It's almost an accessibility thing for me these days.
