It is daft, but people will watch anything. MMA definitely doesn't need it, as it has grown hand over fist in the last 10 years, and is still growing. Whether FM needs it for tax etc who knows, but he wouldn't be the first multi millionaire to run into money problems!
It is nothing but a money making exercise for both men.
If I am up, I will watch on a stream, but I wouldn't pay a penny for it.
