Something I try to do whenever I read articles like this: Whenever you see the name of the giant corporation that the author worked at, replace it with "my team". Google has over 100,000 employees, so there's no real "here's what it's like to work at Google". At that scale, there is too much variance for any simple neat summary (though there are certainly trends and commonalities).
I've met people who worked at Amazon who described it as a hellscape of misery and others who felt it was incredibly rewarding. There's been times when I worked at EA when I loved my job and times when I hated it.
A single data point is useful, but it's only a single data point. I'm glad the author found a better job that fits what they're looking for. That's all any of us really want in our careers.
