Another one of your silly rants? Anyone in a work environment uses the screensaver with password lock, so when they leave their desk they can invoke the screensaver to prevent unauthorized access by another employee. The screensaver would also indicate to others that the employee is still at the office. A message could be used on the screen to indicate when they return. The name has never changed because the term "screensaver" has been known for decades.
