So I can stop argueing since you by yourself showed me how the work is being changed by some kind of interpretation.

The question if Beethoven would agree is not answerable for me, but if we return to Beethoven's text and to the very opening, than the non-musical but conceptual interpretation question arises: Is this the introduction of the orchestre as if the musicians were tuning instruments? The answer to the question will lead you to conducting in this or in that way.
