MongoDB 3.2: Now Powered by PostgreSQL ?

Having said that MongoDB is listening to developers/ecosystem some months ago, today I have read an article MongoDB 3.2: Now Powered by PostgreSQL by @jdegoes that contradicts my own experience.

I will not categorize this article as one more mongophobic article that makes headlines from time to time here and there  like: 

• MongoDB has 'architectural' problems and has done nothing to improve 
• 600TB MongoDB Database 'accidentally' exposed on the Internet

Although I understand writer has some personal interest as he has invested in mongoDB Analytics, I have to admit that he is making a case that technically looks very sound to me "flattening out the data and using a different database to execute the SQL" is not the way to go for MongoDB BI solutions.

I also agree with much of his arguments when he tries to describe of what is going wrong with mongoDB's ecosystem.

Still I am not as pessimistic as the writer and I hope that:

• a) This connector to BI tools is only a temporary quick fix solution and there are better tools coming in the pipeline.
• b) MongoDB will listen to his arguments and comes with a revised policy regarding its partners and the ecosystem at large.
  The story of how $lookup ended up been part of community edition makes me believe that mongoDB can do that.
