Probably because it was so. I remember watching it and thinking "finally, they're listening to us Trek fans!"What happened in season four of Enterprise was pretty accurately described as a "reach-around for the trekkies who hung in there until the bitter end." It was the closest thing to pure fan-wank that we will (hopefully) ever see out of the studio.
Why do you think this is so?
That's redundant. "It is because it is" isn't much of an argument. Be specific.
