Yes it's seemingly the go-to rebuttal, I've lost count of how many times I've seen it with barely any variation.

Not sure if it's a product of LessWrong or Slate Star Codex or something. I kinda suspect it might be LW, given how it superficially resembles an unanswerable philosophical paradox but in reality is about as challenging as a question posed in a 200 level philosophy course like introduction to ethics.
