None of the prompts being demoed were offensive, only the outputs, so that wouldn't have helped. As to why they didn't test the outputs of prompts like "images of German soldiers in 1943", that's probably due to the belief in symbolic determinism that underlies their behavior. The hard left is a big fan of the belief that reality comes to reflect its symbolic representation, not that symbolic representations reflect reality. In such belief systems depicting something symbolically can make it come true. An example of this in earlier eras was the Sapir-Whorf hypothesis. This shows up as changing the race/gender/sexuality of people in art forms like job ads or on screen in an attempt to change job demographics in reality, but it can also show up in other ways. For example if you believe in symbolic determinism, then drawing Nazis is dangerous because doing that actually creates Nazis in reality (or in weaker forms of the belief, increase the probability of people's beliefs becoming more Nazi-like). Remember that 50% of their effort went into stopping people drawing pictures of white men even when that would be highly realistic, because they believe that depicting us directly creates problems in the real world. For such people testing prompts expected to produce only white men would not only be risky in a careerist "what would HR say" sense, but it's perceived as risky in its own right! The very act of testing could make the world worse. That's the whole reason they're trying to stop users doing it in the first place! It's also why they constantly bring up physical safety even when talking about symbols. So the Gemini team have ignored the actual feedback they got and decided that the error was making groups of bad people diverse. They're going to fix Nazis and Vikings to either refuse to depict them at all, or to show them as all white men (because those groups are bad), but ignore all the cases where groups of good people get incorrectly diversified. And of course they won't do anything about the text. This is all predictable given their beliefs about the nature of reality.
