Musk’s gesture has received mixed reactions from politicians and academics, with some likening it to a Nazi salute and others saying it was an accidental action made in the heat of his victory speech.

The Roman salute is conditionally allowed in Italy and outright banned in Germany. German chancellor Olaf Scholz responded to Musk's gesture by saying, "We have the freedom of speech in Europe and in Germany," he said, "what we do not accept is if this is supporting extreme right positions."

Elon Musk responds to the criticism over his one-armed gesture during Trump's inauguration which sparked controversy.
