I think you need to consider the followings - There is nothing wrong with Proprietary software. MongoDB is vilified because they built community on the assumption what this software will be Open Source. Because of this many spend a lot of their own time helping to promote MongoDB and one day MongoDB changed their license. Amazon's DocumentDB makes no Open Source promises - Your competitors can copy your software is one of the downsides of having your software Open Source. You however may get much better adoption curve in return. - This is not MongoDB boycott. If repository promises to its users it will only contain Open Source software and MongoDB is not any more it naturally has to be removed. Keeping it will mean breaking promise to repository users - MongoDB can't compete with AWS is quite far fetched statement. Competing with AWS could possibly slowed MongoDB growth of course.
