You can compare selling a database to selling git. Nobody is selling git itself, they sell the hosting around the tech, or create a dev workflow (gitlab) that uses git at its core.
If anyone tried to sell git itself it would be impossible. I never used mongodb for reasons listed in the article. But there is free and open source and resilient postgres.
the companies who succeeded around git did not build git. it would be a tough thing to develop both git and the hosting / workflow business around it.
so I guess the lesson to learn is don't try to build extremely sophisticated software as a startup where there are already good enough open source alternatives.
