Good points. For what its worth there are other successful MongoDB hosting providers - mLab (originally MongoLab), compose (originally MongoHQ), and ObjectRocket - so they (MongoDB, Inc) don't have complete control over the ecosystem, despite the AGPL licensing. Well, they do have the market for support cornered, but long term the margins on that are much lower than DBaaS. I think a larger issue for MongoDB (& Hortonworks/Cloudera/MapR) is Amazon/GCS/Microsoft hosted services that obsolete them for many use cases. MS already has Azure DocumentDB that supports ACID transactions and has a MongoDB compatible API.
