None of which are in this picture. The person in the picture talks only favorably of immutable systems yet is apparently against them, thus making for an easy target by arguing against themselves, so a straw man.
I’m actually positive to immutable systems, I just thought the argument wasn’t great. I realize that’s about what Skinner does in the meme, but it feels weak.
On second thought, I think the reason it was so jarring is because normally points against Skinner are in top picture, and the bottom picture has him abandon that line of thoughts in favor of something simplistic, thus changing his mind from one side to the other. Whereas here, the points against Skinner are at the end point of the meme, and thus he argues in both directions simultaneously.
