404 media is really, really anti-ai and especially image generation. In this case stolen isn't as inaccurate as it could be but the article definitely has a strong bias. (Stolen in the same way a musician can steal a chord progression, i.e, not illegal but done faithfully enough sorta unethical)
Everyone violently pro- OR anti-AI should realize they're violently agitated before any word is spoken. The most plausible explanation to this phenomenon is that, AI image generators trigger Uncanny Valley effect[1]. It might have hit the bottom, or there could be more below, but either way, people should be aware and be mindful and be interested in that they are more agitated than with respect to superficial agreeme…
Also, ai art has gotten past uncanny valley in a lot of cases, that's why there is concern it's possible to confuse with real images.
