I think the reality is that many large OSS projects are corporate sponsored, either directly or via companies paying developers to work in the project.
In a case like MongoDB, if the company faced difficultly or even went out of business, the product would undoubtedly be affected.
But since it's a popular open source product that many companies depend on, it seems unlikely it would die. For some of the successful companies using MongoDB at scale, paying developers to work on the project could very well be cheaper than migrating to something else.
I think this is true for large open source projects generally. It's nice to at least have the option of taking the code into your own hands if the company or people developing it decide to stop for any reason.
