When you brake to hard on a freewheel bike and your rear wheel locks up, its quite difficult to remain in control, you can very easily slip out to the side and fall over.
Similarily this can occur when pressing front brake, that too can slip out.
On a fixed wheel bike the majority of the speed modulation is done with your drivetrain, so less front brake.
And the incidences where your rear wheel locks up it is much more easy to control, and even use to ones advantage. (note new forumengers asking "how to skid" as they beleive it to be the fundamental form of decelleration)
This is just one reason.
Other might be, it woul be hazardous & simply unpleasant to train at the intensities & speed of summer multi geared riding during the winter.
Fixed wheel riding might not go as fast, but it is an equal or greater workout even at low speeds, which also improves pedalling technique.
Lastly, it means you dont have to get your fancy geared bike all dirty & wet.

Those are the reasons I can think off.
