I've seen my fair share of MongoDB dumpster fire codebases as well and one thing that makes it so much worse is it's almost always MongoDB + noob developers who picked MongoDB because a blog post told them it's all cool and it's a part of a "hip stack". That's the deadly combination. If it was MongoDB + experienced developers who picked it out of careful consideration things would be different. But you never see that because experienced developers are smart enough to pick Postgres instead.
