Edit: This paragraph was incorrect:
The fonts affected apparently include ones like the main Japanese language
font used by the game Genshin Impact, which has 2.8 million daily users
worldwide (no idea of the Japanese user count specifically, but I'm sure
it's over 25,000).
I was wrong about Genshin Impact there. That said, I'm sure you can see the effect with, well, literally any video game or app that uses one of those fonts (including internationally with localization options). Either you're too small to afford it, or you can afford it but you have too many users.
