It's a multitude of things. The LPs are the start of it, but the data oriented culture has been ignored by rto mandate and the head of HR's apathetic response to the remote advocates. Amazon is a very heavy document writing company and more often than not if you had to write a doc you faced someone saying "so what?" and then that person or their/your leaders requiring proving points and writing narratives leveraging facts through data to challenge biases. Amazon's leadership pissed the workers (formerly "leaders") off by instead explaining all mandates and changes are based upon their feelings and beliefs. There is no data (at least any they care to share) and it's heavily speculated to be a 4th wave of layoffs due to the only data publicly available was aws employee surveying demonstrating 80+% of workers wanted remote as a choice.

The other thing often referenced is something of a company culture thing known as "day 1." The tldr there is bezos coined the term day 1 culture to pretend Amazon was always imitating being at launch day status (day 1) and that day 2 is ruin. MThe rto mandate is a cookie cutter example of "day 2 behavior" listed by bezos and his high level leaders.

Finally, there is the hypocrisy. Executives have tons of exemptions, reasons to bend the mandates for themselves, and the power to choose how and where they work, or influence policies involved. Meanwhile, workers have faced a brick wall when it's come to things even medical accommodations for remote. Workers have posted demands from HR forcing employees to at length detail private and embarrassing medical conditions only to auto-decline accommodations after. Workers have no ability to transfer locations that would benefit both the and the company due to red tape from the RTO edicts. Some workers, having been hired full remote, or to a location not where their direct manager resides are being mandated to move across the country due to no exemption stance taken by Amazon leadership.
