Are diffraction spikes of light not present because everything in the picture is a galaxy and not stars? Or do they remove them now with processing?

"While all stars can create these patterns, we only see spikes with the brightest stars when a telescope takes an image."

These distant galaxies are incredibly faint, so I imagine that's the reason there are no obvious diffraction effects.

Yeah, the diffraction spikes in Webb/Hubble images are clues that those stars are nearby within the Milky Way.

Because the aperture isn't made up of nice straight edges.
