The writer uses "deteriorated" as a .... transitive verb!
Further comment would be wasted.

And he is probably relating f/16 vs. f/11 to increased exposure time and
therefore diffraction must be caused by longer exposure. :-)
Some day he'll be corrected.

I came across this strange misconception about exposure time and
diffraction:
" I try to stick with an aperture of around f8 and
not go higher than f11, meaning I try to keep
the aperture close to the sweet spot of my lens,
so I can capture the clearest and sharpest image
I can capture. This is important in long exposure
since the longer the exposure the more the RAW
file will be exposed to diffraction (which happens
at apertures of f16 or more) a phenomenon
that deteriorates the clarity of the images."
It's because the writer doesn't know what diffraction is, only that it's
a bad thing.
