We disagree. And that is ok.

One important note: this is the control flow, not the data flow. The control flow is a workflow engine and each task generates events, some of which trigger additional operations. The control flow was designed to facilitate such interruptions.

I don't disagree with your statement that events get triggered, we write SSIS packages that handle and perform tasks based on events. The issue that I and others have with doing things like popping msg boxes is that you totally interrupt and stop the control flow until there is some intervention to continue it. I could not even imagine deploying a package with a message box to a production environment. On this we do disagree.
