I asked Gemini 3 flash/fast. It didn't fall for the trap.
When I revealed this to be a meme doing the rounds on the internet, it admitted knowledge of this:

So yes, either it's somehow getting finetuned frequently, or else Google engineers tweaked its response to this specific prompt/situation so it wouldn't fall into the trap.
