I didn't feel like watching a video so I looked up an article on the issue. I've got mixed feelings about the overall choice to simplify the family emojis, but the alternative of adding thousands of emojis for every skin shade sounds like a technical nightmare.
Here's the article, written by the founder of Emojipedia, Jeremy Burge (who I know nothing about). It's written as an opinion piece in support of the change, and also has a decent recounting of Unicode's decision making. https://www.mobiletechjournal.com/the-family-emojis-are-now-equally-useless-for-everyone/
It's especially interesting that Apple decided to further generalize the family emojis compared to Unicode's specs. I think I would have just gone with the standard. What do others think?
