This is a very tough situation.
I am not entirely sure what I would do in this case. I also am not entirely sure that GP actually can be related in black and white to the Ferrari team. I think some people are going to blame them for the poor race, and I would not necessarily side with them, but they are in a business. Their business is to win, and they are not going to allow a rule change that doesn't need to be made just to accommodate teams with different equipment. F1 cars have very very strict requirements on all components of their cars, and these are almost all for safety reasons. (the faster the car, the harder it crashes)

As far as the business goes, you can do two things in my opinion:
1) Business look at fiances as the end all say all. Decisions are made so that they can make more money. (Out-sourcing for one). This may not be the correct moral thing to do, but the business is profitable off of it.
2) Many times, Business make decisions everyday that end up costing them money. They don't do it because it was a mistake, but they do it because it pleases the costumer, and in return, this customer comes back again and again. These decisions were made with the well being of the company in mind, not just the well being of the companies bank account.

Ferrari chose option 1. They won the race, they won money, and they won points. Ferrari's bank account is now more attractive, but all the people in Indy and all around look down on them for that choice. Did they make the right choice? I believe that time will tell, but for sure the manufacturers will take a closer look at the forces these cars have because these cars keep accelerating fast, and stopping faster.

The Michelin-running teams? Look into different manufacturer, Investigate the cause and see who is to blame.
The Indy race organizers? Nothing, they had no control because they were limited by the Formula One series sanctioning body.
The Formula One series sanctioning body? Look in to the costs of changing the rules, the pros, cons, and see if another issue like this can be resolved better.
