Basically correct. The diffraction is no longer reinforced along a straight-line. It is still there, but spread-out so much that it usually isn't noticed by the eye. You can think of diffraction as light that does not contribute to the actual image. "Noise" might be the radio equivalent term. Sometimes tricks like curved spiders can spread the diffraction throughout the entire image. While contrast suffers slightly, "spikes" are no longer visible.

One more comment. As I understand it, I still have diffraction with a curved spider. It is just that the diffraction is curved like the stars and planets.
