As someone with several years of experience with both RDBs and mongodb, I totally agree with everything you said.
Also, you got downvoted by the same people that upvoted the stackoverflow post on the problems of downvoting on technical problems on the internet.
People might not like or know the technology and are guided by older tech gurus from the previous generation such as Edgar Frank "Ted" Codd, although he was a genius, now the market is much larger and there's a lot more use cases.
Additionally, most people know RDBs such as mysql and that's what they are comfortable with, i.e. can't get out of their comfort zone and give an honest and good try to something else or don't even have time.
Also it's what's taught in courses as superior to non relational databases.
I would not change our MongoDB clusters for Postgres/MySQL/etc even if I could do it with a single command. In this case it's not relational data though, for a large business relational model I would stick with RDBs.
