Ask HN: How did Dropbox's 'epic' move from AWS work out?

Wondering if anyone here can shed more insight on how Dropbox's move away from AWS worked out 6 years on. I am referring to https://www.wired.com/2016/03/epic-story-dropboxs-exodus-amazon-cloud-empire/ and interested to learn more as we are considering a similar move to one of our clients.
