The logo on this website is 11kb for a 20x20 PNG. Running it through oxipng reduces it to 848 bytes with no difference in quality. It doesn't even need to be an image; the actual emoji would work instead and that would be 4 bytes of data.

I don't know if this is an argument that modern web developers are to blame because they do things like this, or if it shows the author isn't very aware of how to make a small website and his arguments should be taken with a dose of skepticism.

Either way, please, if the author is reading, optimize your images.
