I would argue it's not needed for the last sentence. In fact, when people are freed from convention in contexts like chat programs, they often drop unneeded bits like trailing periods
For example, as far as I can know, your last sentence might have been intended to be: “In fact, when people are freed from convention in contexts like chat programs, they often drop unneeded bits like trailing periods and any semblance of grammatical decency.”
Why does an author publish an unfinished thought? Do you regularily chat with people who send in the middle of their sentences?
I absolutely fucking hate
chatting with people who
do this sort of
stupid thing.
In Ancient Greek, Latin, Hebrew, among other languages, people didn’t end sentences with periods. They didn’t even put spaces in between words. You can tell where one word ends and the next begins because you know the words of the language-and, in most languages words contain certain patterns; for example, in English, certain letters almost never occur at the end of a word, which can help you guess word boundaries even if you don’t know a particular word. Likewise, ending of sentences can be inferred from grammatical structures - although, ancient Latin style tends to involve massive run-on sentences, in part because when the end of sentences are not marked, people care less about how long sentences are. Alphabets were around for many centuries before whitespace and punctuation were invented and standardised.

I do know the local social norms but there is more than one way to illustrate them ¯\_(ツ)_/¯
