I would've thought the same until Microsoft started hiding tank man results in Bing. I'm not so sure if companies will start training different models for every oppressive regime.
Tiananmen Square even shows Tank Man on the first page, 13th and 15th entry, for me. Admittedly, I expected it more quickly on Tiananmen Square; but that might be because I, as a person, forgot that it's also a literal square with more stuff going on at it than a single moment in history.
