I believe we expect moving to the cloud to be more expensive than running our own DCs as you suggest, but I don't believe that takes into account any 'wasted developer time' you might factor into this.

I believe we started building this platform when AWS was very new, and hadn't seen a compelling reason to transition from it to the cloud until now. There's a couple of posts with more details behind our decision to go to GCP, but primarily it was to leverage their data tooling.
