As a follow faang+er I totally understand the need for rto. Im perfectly fine with 3 days rto like my company and many others adopted which is perfect medium for everyone. In my team we get 3 days intense meetings done from Tuesday to Thursday. The devs have at least 2 days alone times for shipping the code. The company sold the buildings and the remaining building utilization is very high therefore the cost saving is also there. Everyone is happy in the end.
The question is what's the reason to increase from 3 days to 5 days? My guess is that unlike other tech companies, Amazon has high offline presence especially with a global logistic network. They are pressured by the local governments and other parties that if they don't mandate 5 days rto to prop up the cities, they are gonna lose many benefits or deals. So it's probably cheaper for Amazon choose 5 days rto instead.
