I don't necessarily agree with the above justifications, but in my experience this is basically why teams pick Mongo.

It's easier to get started with.

Now there's a truth about MongoDB, it's easy to get started with.

But why is that the top priority?

[FridgeSeal]

Because some devs and teams prioritise “get to prod” above literally all else.

Maintainability? Secondary. Security? Secondary. Data-integrity/correctness? Secondary.

It’s hard to disagree with you on that part. PG is definitely not free to get starts with and requires a bit of setup (hello pg_hba.conf).
