I disagree, I think this is too black and white.

In my opinion, it boils down to what ideas/experiences were seeded.

In this article for example, the author is clearly sharing their first-hand experience, therefore injecting observations from reality and their own reflection on top of it, and they then probably shaped/refined it with AI.

A slop, as I see it, is when you generate content from a very thin prompt and then share it as is.
