No. I've been using that construct long before LLMs and I don't think there's anything wrong with it. It allows you to succinctly state the position you're disagreeing with before putting forward another hypothesis. LLMs overuse it for needless emphasis, with the negative example usually reduced to a single word.

Anyone over the age of 25 actually developed their writing style before ChatGPT came about. Getting all uppity about these surface-level LLM ‘tropes’ is just stupid. I am thankfully yet to run into a situation where someone with this attitude is actually in a position to be able to negatively affect my life. I’m sure that there’s a correlation. Take the “ew, em-dash” stuff back to Twitter.

This doesn't apply here - I don't think? The article claims X; so it is surely no sin for the post rebutting it to straight up state that X is, in fact, not the case.

The LLM tic, by contrast, has a noticeable tendency to be deployed even when X has never been previously mentioned. It is a valid rhetorical technique, and I assume that's why the LLMs have picked up on it - but it has to be deployed judiciously. Which is something LLMs appear absolutely incapable of doing. And that is why people notice it, and think it sucks.

Nonsense. It's a common construction that LLMs didn't exactly invent. I don't think their usage evokes LLM writing at all (not short and punchy enough).

Just because LLMs overuse it doesn't mean it doesn't have its place.

The way the OP used the 'not X, but Y' pattern, the 'X' and 'Y' are two clear, specific, and (most importantly) distinct things, as opposed to stereotypical LLM usage where they're vague characterizations or metaphors. And there's a reason to emphasize that it's not X, because the Slop Cop website implicitly suggests that it is X.
