Why do big companies seem to use MySQL over PostgreSQL

A bit of a deviation from standard soft skills questions here.

I've noticed a pattern, which could very well be biased: while PostgreSQL has gained enormous popularity in the industry, a lot of bigger companies still use MySQL (like Slack or HubSpot, for example).

Is it mostly due to sharding / Vitess or is there something else at play? Or have I just been misguided by specific examples?
