I guess I don't really see the point of your comment in context of this article. The article doesn't mention most of those things you mentioned - it doesn't mention cutthroat culture, or stack ranking, or PIPs. The article is almost entirely about RTO and layoffs, which _is_ a demonstrably large shift in Amazon's culture if you compare, say, the period of 2017-2021 where remote work was encouraged and the company was was rapidly growing, to now.
