As with most things dogma comes with a whole host of issues, but in this case I think it's largely benign and likely did more good than harm.

But that is the result of having multiple applications needing to enforce valid states in the database.
"Business logic" is a loose term. The database is the effective store for state so it must enforce states, eg by views, triggers, and procedures.
Other "business logic" can happen outside of the db in different languages. When individual apps need to enforce valid states, then complexity, code, etc grows exponentially.
