I think there's still a myriad of concerns around the ethics of using others uncredited images to power models that aim to disenfranchise artists.

but my biggest concern is that I think they look tacky, and putting it right in the messaging apps is gonna be ... irritating.

Emoji, Memoji, stickers, now gen images. Can’t wait to start receiving them from my dad and my mother-in-law in the most absurd of contexts. Like honestly, I like how much the older relatives enjoy weird, tacky stuff like this.

Tech people make fun of tacky stuff like this, but it's a big driver for regular people to upgrade quickly.

People have ethical concerns about all the public images that were scraped. Regardless of whether or not we agree with them, it is a pretty popular stance to take.
