alt Hacker NewsAgain, it's absolutely great that Apple does these things!
I was just answering the question of why other corporations don't.
Money.
There's relatively little money in helping the visually impaired. You have to do it because you want to do it. Not because you're going to get rich.
Apple's competitors have had these features for years (Android for 7, Windows for 1), so it's really an indictment of Apple. They give lip service to helping the visually impaired, and this press release is good marketing for the non-visually impaired people who don't know this.
