A major part of the success of open source has been the fact that companies have the option to fork/tweak/sell the code. MongoDB has benefited from this as much as anyone. They gained the adoption levels they have now by advertising these exact benefits. Only later did they decide you need a commercial license to provide it as a service. How many companies would have thought twice about using MongoDB had they thought they would eventually have to pay for it and/or couldn't monetize it themselves? Also, it's not like Amazon is not giving back to the open source community (https://aws.amazon.com/opensource/ https://aws.amazon.com/opensource/)

You don't need a commercial license to provide SSPL code itself as a hosted service if you release the service-rigging code you use to do so. As for the most typical use case, web apps, see their FAQ: > The copyleft condition of Section 13 of the SSPL applies only when you are offering the functionality of MongoDB, or modified versions of MongoDB, to third parties as a service. There is no copyleft condition for other SaaS applications that use MongoDB as a database. https://www.mongodb.com/licensing/server-side-public-license/faq#implications https://www.mongodb.com/licensing/server-side-public-license... Compare their prior, public clarification on the scope of AGPLv3: > Note however that it is NOT required that applications using mongo be published. The copyleft applies only to the mongod and mongos database programs. This is why Mongo DB drivers are all licensed under an Apache license. You application, even though it talks to the database, is a separate program and “work”. https://www.mongodb.com/blog/post/the-agpl https://www.mongodb.com/blog/post/the-agpl Much as Kernel developers published a statement clarifying and limiting the sweep of GPLv2 copyleft, Mongo published a statement clarifying and limiting the sweep of AGPLv3 copyleft. I've heard from a former Mongo employee that Mongo wrote several letters to users and vendors, assuring them that AGPLv3 didn't require release of their app code.
