@mainframed767 @signalapp I wonder if it's out of concern for the attack surface that would expose. Many (most?) zero-click exploits against mobile devices are through vulnerabilities in multimedia processing libraries triggered via sending arbitrary media files.

@mainframed767 @signalapp nice attack surface, upvoted! :)

@buherator @mainframed767 @signalapp Signal has stickers ¯\_(ツ)_/¯

@mainframed767 @DaveMWilburn @signalapp My guess is it's a schema thing. Reactions currently would be a reference to a single Unicode sequence, whereas custom emoji would have to be a URL (to where?) or b64-encoded data

@schrotthaufen @mainframed767 @signalapp can you customize those?

@buherator @mainframed767 @signalapp You can create a sticker set in Signal desktop https://support.signal.org/hc/en-us/articles/360031836512-Stickers#sticker_creator_steps
