> Hearing some places just have one giant database where all teams can add and remove columns is... Kind of scary to me.

Are you talking about Bank of America? My impression from the interview was that it is not a free for all but rather all teams are equal but some teams are more "equal" than others (compliance). I still don't get why they need write/execute access. I would be OK with other teams having read access to my database.

There was a discussion the other day about using views as an external interface to a "service" so basically we maintain rest, gRPC, or whatever but if other teams just need read only access to our data, we can expose a view to them

Assuming people will need reports that cut across team/microservice boundaries, all that data has to end up in one common place, possibly a data warehouse. At which point, other teams can still add and remove columns and break your reports.

Is there another way to do things?
