Low Tech Magazine Article on the whole site...which mentions dithering: https://www.lowtechmagazine.com/2018/09/how-to-build-a-lowte...
"""Compressed through this dithering plugin, images featured in the articles add much less load to the content: compared to the old website, the images are roughly ten times less resource-intensive."""
There's an assertion which implies data, but no data.
But accepting that there was SOME comparison to specifically their "old" image method, the takeaway could be "re-evaluate your optimizations"
Another take with low-tech mag is an aim of describing and utilizing old techniques that did the job just fine (a sentiment I take from a lot of their articles). So, using the latest compression algorithm literally doesn't tick as many of their boxes as dithering.
I don't have the numbers handy anymore, but I did some testing on that assertion and their dithered pngs look absolutely worse than a JPG or WebP of the same filesize, as you'd expect.
the "data" comes in the form of a before and after perf-test:
