User management, documentation, distribution, UI’s, upgrades, high availability and clustering, backups, libraries, skills required to administer and therefore hire for. I’ve worked in companies where we grabbed any tech we want, and I’ve worked in companies with one default DB unless you had an excellent reason. The latter meant a much simpler universe where entire teams knew how to fix things that broke at 2am. You just hire one type of DBA. It also meant dev teams really knew how to squeeze the one DB platform rather than learn a little about 10 database types.
