You went digging through my Reddit comments to find a two-month-old thread, that must have taken a lot of effort. But I'm afraid I don't see what the relevance of it is, aside from a general "it's about AI". The bulk of the comments I wrote there were about water usage.

I'm genuinely puzzled. Are you saying that deduplicating data is "hiding unethical behaviour?" It's actually intended for improving the model's performance, having a model spit out exact copies of its training data means you've produced a hugely expensive and wasteful re-implementation of copy-and-paste rather than a generative AI. The whole point of generative AI is to produce novel outputs.
