I guess Truck-kun wasn't enough so they needed to start setting up "MC-Motels" to lure them in by the thousands. I guess when technology advances enough its just better to have them demo the world before you send them than just drop them right into it through death and a few words of "I am god, my bad, ISEKAI!" or whatever.
Perhaps this just widens the net to those who wouldn't be able to handle an abrupt change. I mean it even asks first.
