As it is their "duty" to twist the truth in this way, it is our role as the users of these technologies to present things as they are.

No, mongodb’s PR approach and results were largely uncommon at the time. They didn’t advertise directly but instead targeted and amplified dev communities - as detailed in the article linked earlier.

The result was that people not associated with mongodb talked about mongodb at various dev conferences and in blog posts. People didn’t want to listen to PR teams then too, but they followed their peers.

Again, I will stick to saying that if you use technology you have no experience with, the problems resulting from it are on you.

Testing out technology on important projects is reckless and is a risk a lot of people take but push away any responsibility for.

As a professional, before I suggest to use a technology at a project, at first at the very minimum I spend some time with it to learn the ins and outs. Every technology has cons. Just because you don't know them does not absolve you from responsibility for them.

The reality is that most applications are boringly similar once you define the problem in simple words. There is very rarely a need to use new technology. It is my experience that it is usually better to use technology that is not necessarily cutting edge but one that you know well and that you can easily hire people who know it well.

Because no technology is perfect, but it is much better to know the cons ahead of time and know you will have people who will know the problems and who can find reasonable solutions for.

I am personally sick and tired of people who first advocate for new technology to be added to the project, touting its supposed benefits, not knowing the cons, then don't want to take responsibility once we actually find the dead bodies.

The funny thing is that they chose Mongo precisely because they were familiar with it...

MongoDB came into the community like a ton of bricks, taking over conferences, flooding the zone with mugs and t shirts, and for a time there, you couldn't view the front page of hacker news without at least two MongoDB posts. The death of SQL, now known to be an inferior relic of the past, was a regular topic of discussion. There's a reason why the "Web Scale" meme is so famous, because that's what actually happened for awhile there. SQL was an inferior, leaky abstraction, and ACID was not "web scale". it became all about the CAP theorem (which I hardly ever see anyone writing about these days).

only a year or two later, when teams that went all in on MongoDB at the behest of MongoDB's marketing department started realizing they'd been sold a bill of goods, did the slow and arduous march back to what continued to be the best generalized solution for 95% of data problems, the ACID compliant relational database, begin to occur. given that, this blog post seems really behind the times.

mongo was absolutely one of the most egregious (daresay dishonest?) purveyors of such myth. it was quite off-putting for me and my team.

As a counterexample, Azure Cosmos or Amazon DynamoDb are marketed as specific solutions for specific problems. Other RDBMS like SqlServer or Postgres are marketed as general purpose solutions because they are in fact general purpose solutions. Mongodb, on the other hand, is a specialized "document database" marketed as a replacement for relational databases.
