On my end, I've noticed something quite curious regarding a similar topic.
I'm not a native English speaker, so it's obvious that I'll never be perfect.
So when I started writing my novel, I first wrote it in English and then translated it myself. The result was understandably terrible, with bad reviews and comments everywhere complaining about the grammar and language despite the clear warning from the start.
It's okay, it's valid to want to understand a story.
So I set to work on improving those first chapters, retranslating them, rewriting them a bit differently. When the AI came along, I used it to translate the chapters better and even checked every word again to see if they made sense. I even ended up redoing the first 25 chapters altogether.
The funny thing is, people still complain about the grammar no matter what, according to some comments, it seems like I'm writing in Norse runes or something. Despite the fact that they might be reading the revised 4.0 version of the chapter.
And then I started to notice something, a pattern.
Since I never deleted the chapters as such, I simply edited them by deleting all the letters and rewriting everything, the comments were never deleted.
And I understood that new readers only saw the comments complaining about the grammar and they also started to complain about the grammar and how poorly written it is, without ever saying exactly what's wrong or how to fix it, they just "feel in the force" that something is wrong.
