New Salute Emoji

This is a user-to-user forum, not a way to contact Apple. And no one in this forum can answer a question that begins with “why”. You can let Apple know your thoughts here→https://apple.com/feedback

Neither Apple, nor other manufacturers create/approve emojis.

They are approved by a specific organization, reachable at this website https://unicode.org/emoji/charts/emoji-list.html, so your comments/requests should be submitted to them directly.

Thanks and regards

Giulio
