It's not silly, it's just the most convenient and broadly relatable failure mode. I mean, I could compile a 20 bullet point copypasta detailing everything from prompt injection to exfiltration of sensitive data as-a-feature but if touts are willing to stoop to ignoring all of that while arguing obvious reductio ad absurdum at face value there appears to be little point at tilting that windmill. The Bullshit Asymmetry Principle is definitely winning here.
