The bad thing here is that modding discord will become significantly harder and might have been their original intention here.
They can just repackage the web app and mod that if all else fails.
oh won't someone think of the discord mods!? If its too hard for them to mod, they won't have time to groom children.
They’re showing how easy it is to vibe code a port of the app. A motivated developer outside Discord could do the same and release OpenDiscord or whatever if they cared enough to want to mod the app that way.
