Politically, Max supports Ferrari, and vice versa. If Ferrari didn't support Max, he most likely would not be in the position of power he now enjoys. So it's in his best interests to pretend that F1 would languish without Ferrari. History has shown otherwise, where other major players and contributors have died and gone away, while the sport continues to grow and be more profitable.
The same scenario would play out of Ferrari did not compete in F1. For a couple of years they would be missed, but someone else would fill the gap, and after a decade, most fans would say "Ferrari who?". From the late 80's to the late 90's Ferrari were just a competitor. They did not lead by innovating anything memorable, they were not considered serious contenders, they were just there. Mind you, having Ferrari compete in Formula One is a good thing, but just as same as anyone else. it's good to serious competition between serious players. Witness what's happening this year, where Shu and ferrari have returned to competitive form against the dominating renault, and it's good, it's made it fun for the fans. The same rules applied when Ferrari dominated. It's good so see serious contenders, a close battle, and interesing races and fans. Some Ferrari fans want that team to dominate every race, and that's not good sport, that's just a guaranteed result. Good sport comes from hard competition and the risk of failure. Otherwise, it's just play acting.
And that hurts the sport, and makes it a joke.
