The image aesthetic is emulating the appearance of a dot-matrix printer. It's just a low-tech motif to go with the publication.

  That would be all well and good, but the page specifically claims that using dithered images lowers energy use.

    They may have ran metrics on decoding processing time neé energy usage

      I doubt it. The only study I could find on energy usage in image decoding was this https://ieeexplore.ieee.org/document/7168333 https://ieeexplore.ieee.org/document/7168333 which found JPEG decoding to be much less energy intensive than PNG decoding, mostly because it's faster. Note that that's not just a function of file size, as lower quality JPEGs actually took more energy to decode. Which all makes a lot of sense when you consider how much work has gone into optimizing frequency domain based compression and decompression.
