This cartoon does sort of accurately illustrate how Muller’s Ratchet works, but like any metaphor, it drags in a lot of baggage.
Here’s what I don’t like: every step involves intent. In the metaphor, every change has a purpose and brings in a functional element in addition to the random noise and degradation, and the recombination step is portrayed as combining specific, useful parts. Intelligent design creationists will love this cartoon, which is too bad.
I guess my primary objection is that last panel that says “…if you have an image editor that lets you spice together parts of two images, you can make a new version with the best parts of both“. Recombination doesn’t discriminate what parts are best. It’s random.
