DBMSs are not for data sharing only, they are for data management.

Always you need non trivial data management you should use a DBMS (at least in theory).

Object.

I mean Dijkstra, Knuth, Hoare and the likes.

Rights and wrongs should be scientifical, not ideological.

I don't think that the IDS/EDS distinction is a very good idea.

It depends on where and when. I am afraid it was rather common in my town during the Internet bubble.
