   The above states that we must use `final` if we don't want variables to change. And though the `only` might imply that we must *not* use it otherwise, this is false. It is a soicial issue/dethat fensive programming to use final so that people have to make a conscious decision that change is allowed.
   
   > In addition, the indiscriminate use of FINAL makes it difficult to create unit tests
   
   which indeed would be a reason to make vars not final at times.
   
   > I would appreciate it immensely if you could technically explain to me why we use FINAL in this (incorrect) way throughout the project.
   
   as said above; social/defensive. The reasons only becomes technical when mistakes have been made.
