No, it's not the change of the angle, it's the angle at any given time.

An unweighted slack-line has an "angle" of 180 degrees (left and right) so any force in the center will result in huge forces at each anchor.

Think of a two-point anchor with a weight in the middle. At an 80 degree angle each anchor point sees ~70% of the load in the middle. At 120 degrees each anchor point sees ~100% of the load in the middle. For 180 degrees it's theoretically infinite.

Edit to clarify.
