For Amazon, they have company offices all over the world. For many projects, there's a good chance you may need to work with people from several other offices, and may need to take early morning meetings to overlap with people from Dublin, as well as late night meetings to overlap with people from Sydney or Tokyo, and everything in between. So, those meetings are going to be on Chime. Or Slack Huddles. And either way, once you're doing that because some of the people are remote (in another office), you might as well do that because people are remote (working from home, wherever home might be).
