this comment points out the same things as you. It's (not-so-obvious but pretty clearly in hindsight) sarcasm

I thought it was sarcasm, then got confused because people seemed to take it seriously. So I decided to try the prompt on Gemini 2.5: Pro just says it can't generate an SVG, Flash generates a petty great one. Whatever copilot is using is also good. So I just assume even the image generated is a joke? People are starting to make me doubt my abilities to identify sarcasm.
