There is also;
-Rakshasa losing cat and getting a full redesign. This was part of seemly them soft-rebooting Tarkirs flavor (no word fully give but was part of Khans coming to arena). This also why naga are now snakes.
-Efreets are now Djinn. This is part of Tarkir as well.
-Cephalid are now octopi, this them now wanting animal-folks to match what animal they are folk of.
Fist off, everyone hide the Homarids.
Likely crabs, a crustacean creature type would be better though.
Wasn't the Rakshasa thing for cultural reasons at least, same with efreet I assume. The other changes are just bizarre. I guess they want to allow people more typal stuff to be easier idk
Yes and no. Rakshasa being cat people has no mythological base and something DnD put in. People where NOT offended by this but more expressed wanting something more faithful to the mythology.
Myth wise efreets are just types of djinn and magic lore hasn't really done much to separate the two out enough or have their own twist to really show why they should be separate.
Nagas I can't be sure of, best guess is that myth wise naga are closer to being gods/demigods/angels than just snake folk. I also wonder if Neon Kamigawa had something to do with it since it had non-naga snakefolk and snake tribal already being a somewhat of a deck.
Cephalid and viashino are falling in line of beastfolk in magic being the animal type they are (leonin are cats, aven are birds, ainok are dogs) if they are not drawing from a specific mythology. If I had to guess why this is happening I think it's likely Bloomsburrow having lizard people and the line between cute critter lizard folk and viashino brining up if viashino should just be lizards.

It's a bit of a fine line for that. By rights, if they apply their metrics evenly, they should probably be getting rid of angels and demons for the same reason, but they won't. (Not that I'd want them to either, to be upfront)
Maro touched on it, they would be willing to rework or de-flavor angels and demons if people from those faiths expressed feedback on how they want them to be better. Seemly most people of western and Christian traditions currently are mostly fine with now magic has used their mythologies while those of other places have expressed a desire for magic to be more accurate as here is there less repression of their stories here.
