I've noticed this! Among changes noticed:
Professional j-school taught proofing/editing symbols changed since the 70's;
Two spaces after a sentence, not one, because the computer prefers it, and it's for easier readability (it's not easier); and
Online dictionaries went Woke, and have become politically correct as far as "use it in a sentence."
The youngest generation is afraid of punctuation, not having been taught it very well by Common Core Schooling. Even Kirstie Alley doesn't use periods at the end of sentences, I don't know - to fit in or what?
I spent a lot of time learning all that. Grammar was a subject of conversation around the dinner table, believe it or not.
