This is weird blogspam based on a Business Insider article from October of last year, which was based on a quote from Amazon's CEO in September of last year: https://www.businessinsider.com/amazon-could-cut-managers-sa...

TL;DR:

> CEO Andy Jassy said last month that he wanted to increase the ratio of individual contributors to managers by at least 15% by the end of the first quarter of 2025.

It appears the rest is speculation and hypothesizing from analysts, which is why they're quoting Morgan Stanley as a source.
