This is just short of asking them to increase the font size... that's an exercise left to the user. Your browser will let you do this via user styles, plugins, user scripts, etc ad nauseam. The OS might even let you do it. On a normal website, that might be a bit much to ask, but this is hacker news. Even so much as googling the term "dark mode" will give you a plugin that does exactly what you want.
