Because like Mozilla, they hate their users. The font rendering in the OS is now utter dogshit. It was changed before Catalina, though.

Apple (and apologists on Hacker News) claimed no one would notice. But a lot of people have, like Trishank, who aren’t even mega-geeks like me. This is what happens though, when you come to despise your users, just as Mozilla did.

We see where that got them.
