I've only every seen people using MySQL at scale if they started with MySQL in prototype and never had the energy to migrate.

Uber also has a giant team dedicated to re-inventing slack. I'd take their engineering prowess with a grain of salt.

Lots of people do dumb things for dumb reasons.

Most developers I interact with, even the really good ones, are profoundly stupid when it comes to databases.
