There's a hundred pictures of public figures doing the same gesture, and with not even the hand on heart precursor, so it's pretty clear the 'Nazi salute' is your uncharitable interpretation.
A still photograph is not the same as a video. Part of the trajectory of a wave can involve the arm being at the same angle as a Siel Heil salute. But Musk's salute was not a wave. It was identical to a Sieg Heil, but for the touch of the breast at the start.
There are not "a hundred pictures" of public figures "doing the same gesture" because a still does not capture the full gesture.
There is a reason why neo-nazis have recognised and welcomed Musk's salute, and Jewish leaders, including former ADL head, have condemned it.
