The brown comic image is a dead giveway too, does anyone know why so many of these have this weird pastel / brown color? I mean it fits with the theme of the page so it might just be confirmation bias or chance (that is, I don't notice the AI generated comics that aren't brown).
Alternative: the author actually wrote the words (because that's their opinion, and they want to share it to the world) and generated the comic with AI (as it's just a way to illustrate, and they're less proficient with drawing than with writing.)
I dabbled in writing, I would have hated for random people to assume my posts where AI generated, especially given that such a claim is practically unfalsifiable at this point.
One theory is it is the feedback from all the Ghibli stuff that went on a few months back. These tones first started appearing there for skin tone or even sky, then started appearing everywhere.
