It’s old-fashioned informal writing. Until about 20 years ago, the vast majority of writing was formal writing. Formal writing follows formal speech patterns, with proper sentences and commas and full stops. This is what you’d learn at school. When we talk informally, everyday, we don’t actually talk like that. We talk more in fragments. An ellipsis is sort of the old person’s way of separating these fragments. Younger people tend to press enter and send another message to separate the fragments. Maybe the oldies get annoyed at young people sending multiple messages when it could have been one.
