MongoDB Atlas's Forced Upgrades and Support Policies Drove Us to PostgreSQL (medium.com)

I'm sure the support from MongoDB Atlas is the worst in the market. It's really messed up that they could flip a switch and kill your production, even after you specifically told them not to. PostgreSQL is a far better database than MongoDB.

MongoDB is like that clingy gf who wants to 'improve' you whether you like it or not.

Old pet turn out to be a parsite, silently killing at each billing cycle.
