What's up with Formula 1?

Hi all,

Just read this piece of news: F1 chaos as top teams quit

Although i had been a dedicated fun back in my university days, I admit i have been away from the sport due to lack of time. It was a big surprise for me to hear these news.

I was wondering, is anyone out there that knows the background behind this? It seems like it is about money, but i cant really understand why.
