You’re not even meeting your own pedantic requirements. The quote says “housing” not single family homes.huh? There are NO single family homes under $1.6M in Cupertino, as clearly shown. And Cupertino is the area defined in the quote. Twenty miles? That's many, many cities, and not what was stated in the article.
To put it in perspective, Apple Park itself is barely in Cupertino itself. 3 sides of the campus are on the Cupertino city limit. There are no controlled checkpoints entering Cupertino and you can cross the border without needing to produce documentation.
20 miles is a relatively short commute, especially when both Apple Park and One Infinite loop are so close to highway exits. Apple has offices throughout the area, not only in Cupertino. By “many, many cities”, you mean you’d have to take the freeway through 2 or 3 suburbs to get to work…
