If Alonso wins the championship by two points or less, then the result will obviously have been affected by that incident.
It was fairly obvious which way the FIA, or to give them their full name, Ferrari International Assistance, would go when making the decision.
If any other team had done that they would have at least had points deducted, and more likely been excluded from either the drivers or the constructors championships, or even both.
Similar things have happened in the past, where one team does something and is punished, but when Ferrari do exactly the same thing, they are let off, or received a lesser punishment. For example, a few years ago a Ferrari ran into the back of a Sauber that was on course to earn the team it's first championship points, but it was knocked out of the race by the collision. The Ferrari went on to finish, but I can't remember if it earned any points. Ferrari were fined something like 10,000$, which is nothing to them. The following race, a Mclaren ran into the back of a Ferrari, knocking both cars out of the race. Mclaren received a bigger fine, and the driver was given a 10 place penalty for the start of the next race.
I no longer watch the races because why should I bother when the results are being openly manipulated?
