Laziness or stupidity. It provides zero benefit with no load and zero benefit on level ground or on uphill sections and the benefit going downhill depends on the load and the grade. Only an idiot would leave it on all the time when it is only going to provide a benefit 1% of the time.
On a 5% or greater downgrade that goes for miles and with a tow load of more than 4,000 lbs. the exhaust brake does help to keep the speed of the rig down with little or no use of the brakes (tow vehicle or trailer).
Clearly they need a truck manual for dummies.
