My reaction when reading this was, "Yeah, but that's because you encoded it in PNG. That's a 'good-enough' encoding, but you can definitely make it more efficient by making it an SVG, since that image is of the kind that's ideal for vector graphics." And then I remembered SVG is a text-based image format.
Touché, frog hop. Touché.
Adding to the point: karma system on sites such as Reddit has incentivized converting text into images, because text posts don't get karma. For example, r/quotesporn[1] (safe for work) has many more users and quotes than r/quotes[2] which allows only text.
As a collector of quotes, this annoys me to no end, because I can't copy/paste the quotes into my personal quotes collection.
