East German here. I have never met East Germans who called their home country Ostdeutschland before the Wende; that was very much a West German thing, and even then not as widespread as one might think (i. e. "DDR" was the much more common name amongst them). After the Wende it became (more of) a thing for Easterners as well, especially in context with the identity: Ostdeutsche(r).
