Thing is, screenshots are fast, and the same technique works across every app. If you work in a field where you might be filing trouble reports from web app A, native app B, website C,... its just easier to use the same technique across the board. Win+S or CMD Shift 4, and move on with your life.

Not nice for the recipient maybe, but hella efficient for everyone else, and there are many more people in the latter camp than the former.
