As someone who is a tech lead for a large database install, I'd urge you to read the rest of the Jepsen reports. They aren't intended to be hit pieces on technology - they're deep dives into the claims and guarantees of each database. IIRC MDB has explicitly reached out to OP in the past (I doubt they'll continue to do so after this).
Why that matters to the rest of us: once I learn all those dials and knobs I'm left wondering why I would choose Mongo over another technology, and how much the design of the default behavior and complexity of said dials/knobs are influenced by their core business.
I would also wonder about the surrounding ecosystem of tooling & libraries.
Imagine there was a programming language which had rather inconsistent naming, poor automated testing support, and a history of guiding its users toward security vulnerabilities. A culture would grow up around that language and the most successful members would be those who could best tolerate those properties. People generally self-select into language communities. So unless some powerful influence pushed random programmers to use the language or made it easier to add new tooling, the culture would continue to undervalue what the language originally lacked.
I suspect the same social dynamic would apply to a database.
I agree. MongoDB has large numbers of peculiarities that you better know before you buy in. It is definitely not so rosy as advertised. In particular it seems the product is not mature (especially if you come from Oracle world) and the features seem slapped on as they go and not thought through.
