I haven't seen a source clearly saying that Amazon had been using MongoDB - I thought the DocumentDB release last week was the first MongoDB product they offered?

EDIT: and searching HN comments, there's multiple people claiming AGPL is entirely banned inside Amazon too

In which case I don't see why this is such a big issue. Amazon couldn't use it before the change because of their licence use policy, and can't after the change either. So the change represents no change in that respect.

Implementing an interface compatible with something that you can't use for licensing reasons is no biggie. Other projects, Free/free/OS/commercial, do that sort of thing all the time.

I wonder where the problem that drove the change actually was... RH dropping it from their distro is an issue related to the licence change, but I don't get the impression that was the intended target.

I should probably find time to dig back into the details, as I feel I've missed something notable.
