The FIA's explanation is as stupid as the actual events.
I would call the entire main straightaway, the sole DRS passing zone, a racing line.
That's has been the nature of F1 racing since its inception though. Their intricate road courses have always been dominated by their wealthiest teams. NASCAR has basically turned themselves into the IROC series with all their cars being a mirror image of each other and that has brought their races into a tighter pack.
