Not letting me use system fonts, even when I'm on Fedora and my font linting is horribly, terribly broken. Maybe I just want the same font on my machine all the time? Why won't you let me do that?
Forcing a font upon me, AND THEN CHANGING IT EVERY FEW YEARS WITHOUT REASON holy shit computers are done just walk away from the keyboard. Just leave it! Security fixes only!
Isn't not letting people use custom fonts an accessibility issue? Could be entirely wrong on that.
