I'm not sure if all those attempts were for real. obviously, FIA knew they were going re-invests the money somewhere else too.
but this is a complete no-sense. I would have prefer the possibility for teams (presumingly the minor ones) to purchase the chassis and the engines they want, bounding chassis and engines makers to make them available for others (the first problem is a sort of espionage, but it could be fixed controlling relationships between teams).
I'm fine with the no-choice of just one tires maker, since there are no points assigned for the tires manufacturers, but the wrong tire can destroy the performance of the car.
For these reason, the points could be assigned in this way: points to the driver, to the team, and to the constructor (eventually to the chassis constructor and engine constructor), GT style.
I would also consider assigning points to fast laps, pole positions, laps while leading and other performance, but that's a little off-topic.
