I think it has a different tone to different people? I had a friend who used to put it after most messages and I thought they were upset with me until I asked. It was just how they wrote. I've also noticed more people using it to indicate a trailing off of voice, not necessarily with any annoyance emotion.

Maybe it’s a cultural thing cause even a trailing voice does communicates the same connotations of being upset. I know of only two buses of the triple dots: showing there’s more content in a quote or to express annoyance.

Some people use it to let an expression breathe a bit, modifying a period to be more like a paragraph break, or a paragraph break to be even a bit wider.

In some cases, that may represent emphasis, and might take it as an invitation to think on what was said because it was especially earnest or important.

In other cases, it might just a cleanser between ideas that don’t have a clear bridge.
