MySQL was a proven solution back in the day, i.e late 2000s. Github/Twitter/Heroku etc were using it. In the past 10-15 years, Postgres has come a long way.
MySQL was always behind in terms of features. In early 2000s it had very limited constraints. Most people were running in ISAM backend and did not even have transaction support. It was being used by people who did not understand how advanced relational DBs were being used. What changed is Postgres overtook its actual competition, which were Oracle, SQL Server and Sybase.
MySQL caught up as well as far as I know, but it still may have some poor defaults that are widely used.
