I reply to these posts on HN relatively frequently these days. These sorts of accusations about Mongo are out of hand, and not congruent with reality. I say this as someone who used MongoDB extensively.

I don't have time to address all of the problems, but let's look at #1 on his list:

1. MongoDB issues writes in unsafe ways by default in order to win benchmarks

This is objectively false. At the time, Mongo chose to turn off write confirmations by default -- this was clearly documented in many places including introductory documentation. Surely no one would have deployed a database without even a cursory skim of the docs, right? The notion that it was done to win benchmarks is baseless. Furthermore, in response to the community's reaction, the default was changed.

This is a recurring problem with the complaints about Mongo. You cannot use ad copy to evaluate a database (or any product for that matter, but definitely not something as important as your primary data store). You must read the documentation. You must do a trial run and make sure it will meet the needs of your use case.

You can't be upset about the results you didn't get from the work you didn't do.
