Some of it may be an age thing, in my own case, i dislike emojis because i have no idea what most of them are supposed to mean., including the one at the end of your post. So for older folks like me, they make the post look weird, and can make it more difficult for me to understand what it is that you are trying to communicate.
But i wouldn't actually downvote you for it, im just more likely to ignore your post if it is overflowing with emojis.
It has been several years since I have read these, but if I recall correctly, he clarfies the reasons why later in the book.
