I hate websites that only have dark mode if you sign in. Sometimes they even default to the system theme when you’re logged in, but force light mode when logged out. What the fuck? What? Why? Just don’t. Ever. If you have a functioning theming system that you enable by default for logged in users, enable it by default for everyone and auto-sync the theme (unless maybe you have a very specific colour scheme important to your content—but you still should have the themes for accessibility)
