I've noticed it being heavily used in non-native and accesibility type situations.
To them, people who do not necessarily spend swathes of their day reading generated text, it does not sound any particular way other than "yes, this is what I would like to communicate to my perspective audience".
It's really becoming a sort of cultural thing in which one people (from your culture) are turned away and another people (from the author's culture) see it as a massive benefit.
To me, the bad thing about generated posts online aren't their existence. I've already spent a life clicking off of blogs and posts I don't like. Perhaps as much as 90% of the web is not made for me, and that has alway been the case. What I've never understood, which has also existed forever but less so here, is people who will spend their time adding nothing of value to a conversation adding only some complaint about something as trivial as the writing style. You know, the commenters who take their time to click on to a video and actually type out "this dumb you dumb" without offering any kind of constructive criticism or engaging in the conversation at all.
Like, you wouldn't do that in public, would you? Walk up to someone with a shirt you don't like, say that you don't like it, and walk away? "Why even go out in public if you can't be fucked to dress yourself?"
