Love the six-fingered thumb-down image in these stickers! https://narrativ.es/@janl/116907298750581216

Following links in the comments, I found the design (by
@VillageOneCoop) here:

https://github.com/village-one/stickers/blob/main/generative-ai-nein-danke/v01-sticker-generative-ai-nein-danke.svg

It's licensed CC BY-NC-SA 4.0, so I hope that they won't mind that I used inkscape to edit it into a "Thumb-Down-AI" image with just the six-fingered hand. I think I might find occasional uses for such an emoji, and maybe others might like it too.
