I've never come across the period-as-negative idea before. From the discussion here, it sounds like in-group signalling. For me, punctuation is an unconsious part of writing, and it would take special effort (or a browser extension) to remove it so as not to be marked as an outsider.

I'm so confused why someone would jump to "I don't do it" to "it must be an in-group signal". What group would this even be?

I mean, even iOS specifically makes it easy to end a sentence with a period by making a double-spacebar make a period.
