Should cruise control be used in wet conditions?

I read that it's not wise to use the cruise control when driving in wet weather, of which there's plenty about at the moment. Can you elaborate on this, as I am unable to get it across to family and friends?

A long-winded American alarmist chain email was doing the rounds. Basically, if cruise control was set to a speed and the driven wheels began to spin, the cruise control electronics would increase engine speed to try to get the car back to the road speed set by the driver. This would increase the wheelspin and could easily result in a total loss of control of the car. The same applies in icy conditions.
