I'll be even more contrarian: I don't care if someone didn't write it as long as it's good (that's the major problem). I don't mind people using quotes when writing either. It's just that typically people (used to) curate their words before presenting them as writing. Although I'd prefer it if they also credited/explained what they used to write it in the case of heavy AI generation.
This, really. If I am entertained and learning then I do not care where the content came from.
Of course Claudeish or GPTish ("unusually") will easily push me away. Just like any repetitive or obnoxious tendencies that might appear in human writing.
