Why is "Torsion mangonel myth" trending?

Wikipedia Overview

The torsion mangonel myth, or simply the myth of the mangonel, is the belief that the mangonel was a torsion siege engine which used the tension effect of twisted cords to shoot projectiles. As an extension of the concept of a torsion-powered mangonel, some believe it was used as a siege weapon until the arrival of gunpowder artillery or that it was the only or primary siege artillery before gunpowder. In reality, the vast body of contemporary evidence in art and documents point to the mangonel being a machine operated on manpower-pulling cords attached to a lever and sling to launch projectiles. Evidence for the usage of torsion siege weapons such as the onager exist only up until the 6th century, when they were superseded by traction artillery.
