I've been called out more than once for using too much italics in my writing.
But the trick is I usually write like I would speak. This leads to italicizing any word or phrase I'd speak emphatically. (Which, yes, I've also been called out for doing a lot when I speak. So what; I've also been told I'm good at getting my point across. I'll take it!) In any text important enough to go through multiple revisions, or to be written from the start with multiple revisions in mind, this characteristic is diminished. But most text is more throwaway, just like most speech, so it gets left a little rough.
This also tends to feel pretty natural. If you read LLM-written text out loud, or the prose TFA is talking about, it... does not feel natural at all. So what I'm trying to say is: some level of emphasis is just fine. Don't overthink it.
