Apple has had strong accessibility features since before they were a household name, when they were a fraction of the size of the company they are today.
Ironically, I think the accessibility focus started because they were a fraction of today’s size: in the early 2000s, section 508 requirements were becoming more stringent; there was an increasing risk that Apple would get shut out of government contracts, and due to the small market share of OS X, it was not considered a viable market for commercial screen reader vendors, so Apple decided to roll their own.
Thanks to strong leadership in the accessibility team, there was an increasing buy-in from the top, and throughout the company. Today, accessibility is indeed in Apple’s DNA, but initially, there was quite a bit of genetic engineering and (dare I say it?) government regulation involved.
Apple was known for easy to use in the 1980s. While that isn't entirely accessibility, the two are related. The early macs had some accessibility features.
Evidence is simply being brought forth to showcase that before Apple became as large as they did, they still cared about accessiblity, irregardless of their "company size" as you stated.
I don't see how that's relevant at all in 2019. People WERE giving Apple mad props for their thoughtfulness back in the day. Now, they have revenue over a third that of Saudi Arabia's GDP. I was responding the OPs point. That's evidence for an argument nobody made.
Here's a post from 2006 for example, talking about accessibility in Mac OS 9: https://discussions.apple.com/thread/724948.
Here's about accessibility in Mac OS X Tiger (2005): https://en.wikipedia.org/wiki/Mac_OS_X_Tiger#Accessibility.
