As far as I am aware, AWS never used any of MongoDBs source code. They implemented the MongoDB API. The license is thus irrelevant. AWS could have implemented the Mongo API no matter what sort of license it was under- it could have been entirely closed source.
Its no different than Google using the Java APIs in Android. The Supreme Court of the USA clearly ruled in Google's favor. It did not matter that the APIs were closed source software.
Further, I would disagree with using the term "freeloading" for some one who uses an Open Source program under the terms of the license in which it is offered. (Again, not even the case for AWS as pertaining to MongoDB).
Yes, they did, when MongoDB was licensed under AGPL. After MongoDB relicensed under SSPL, they release the API-compatible DocumentDB which is proprietary itself.
Sorry, I did some duck searching, maybe I am misremembering, but I can't find any evidence that AWS ever used MongoDB or offered it as a service directly?
