I've worked in tech with large teams with people of all sorts of backgrounds, in English, often broken English, and nobody cared.
AI, when people think they see it adds an air of dishonestly. Is that person there to scam someone? Did they even choose those words carefully? I do not know.
It makes conversations difficult now that you are second guessing everything.
Broken grammar in my experience both seems more sincere, and is more accurate.
