First, the Fox Box is no more. It was re-branded as 4Kids TV in January 2005.
Second, Jetix and 4Kids don't need to go away just because you don't like what they have to offer. The fact is that both blocks put the butts in the seats and are raking in money and ratings, so they're not going anywhere. Therefore, yelling that they should go away or get canned just because one guy doesn't like them is as futile as setting a place at the dinner table for Amelia Earhardt.
If you don't like what 4Kids TV and Jetix have to offer, simply switch them off. Just because something is on doesn't mean that you have to watch it.
