The real reason outside all the bs: WOTC are afraid of being "canceled" so they have been outright retconing very large parts of the lore to avoid being labeled by random people all the common names on the Internet.
If you like dnd lore this game will definitely disappoint. Instead I would suggest just looking at it as it's own thing. Races are really different human sliders. Everything is watered-down. Everything.
Sadly this post is 100% correct.
Race in this game means nothing more then some attribute bonuses and cosmetics features.
If you look at recent videogames they are all starting to include hooved/horned humanoids as playable for some reason (maybe some conspiracy by IRL demons and devils to make themselves more acceptable before they take over out world) and WoTC joined the trend as well so as to not fall off the bandwagon.
The only comfort we have left is that we can kill NPC we don't like.
