I am not at Amazon, but at another FAANG, also am in Seattle, and it is the same thing for us. If we were hit with RTO, it would make exactly zero sense for my team/org.

Out of people I work with, one of them is also in Seattle, another one is in Toronto area, the team lead is in SF, the manager is in SD, and the skip level manager is in MTV. I am not even gonna talk about people on the partner teams that we gotta work with, as they are all spread out all over the place. RTO would be an absolute net negative for every single person on my team, as we aren't going to see the people we work with in our local offices regardless.

And don't even get me started on trying to find available meeting rooms in the office for meetings that were not scheduled way ahead of time. If someone wants to hop on a call with me for a debugging session or has anything to discuss impromptu, being available for that in the office is rather difficult. All while I can hop on a meeting call on a minute's notice when WFH.
