I don't understand how it is legal for an organization to limit their constitutional right of expression? In addition they are not even employees of the FIA.
That being said, it really sucks the hypocrisy of sport business now, world cup, F1, Olympics, they are all claiming that sport help all the world to gather in peace and being good to humanity, when in reality it is like everyone shut up to our dictature to ensure we can make the most possible money by having the smoothest contradiction possible.
If it would help them get more money from advisers, they would not care having someone executing in backstage...
