No. It's not creator-janitor thing. It's rather the situation that programmer A makes a huge technical debt, and programmer B must pay him off. It's poor code design, poor code management. It's more like: - irresponsible house developer builds house very fast and very cheaply but he doesn't care about safety or design - then building is beginning to collapse and tennants have to hire another developer to fix mistakes of previous developer. They must pay twice! One time - for creation of the building. Second time - for fixing.
