Yep, as the sibling said, it’s to prove the point in a snarky manner. The yellow-on-white color, the wobbling, upside down path of text, the font choice, the unrelated image; all of these serve to make the concept actively hard to process.

Hopefully this sparks a little “wow I wonder if my image of text was also hard to read like I just experienced” moment.

It actually enhances the message by being harder to read.
