Don’t think it was the right decision. A three place grid penalty or no penalty would be better
it seems clear there was no performance advantage. So if there was no performance advantage, such a draconian penalty is not appropriate. The purpose of penalties should be to neutralize advantages gained from cheating. In this scenario it seems they accept no advantage was gained, and there was no intent.
We have also seen penalties this year where the penalty is less than the advantage gained. So it seems these idiots have no idea how to maintain the show. This decision just ended the show.
