This discussion is really confusing me. Are people talking about periods being negative when used anywhere? when used in the last sentence in a multi-sentence message? when used at the end of a single sentence/thought message?

Confused.

I suspect people are talking about periods being negative specifically in IM/text message contexts, like Slack, where "send message" has taken over the role of period and period has morphed into an extra signal for something like "finality."

For me, only when used on a single short message sentence. Long explanations and paragraphs get punctuated at usual.

I'll also add I'm not the arbiter of what is and isn't correct or wrong, just explaining my own opinion.
