It's not so unbalanced. Ferrari has a history of cheating.
I was just re-watching a program on the Shelby Daytona Coupe. In 1964, the Daytona Coupe had the advantage to beat Ferrari and win the sports car championship at Ferrari's home race, Monza. Enzo went to the FIA and had them declare the event a non-points race, without telling the public or press. As a result Ferrari won the championship instead. If that isn't blatant cheating, I really don't know what is.
After all, FIA does mean "Ferrari In front, Always"
