Outside of bots and spam, third party Discord clients also often disable a lot of Electron's options that guard against XSS stuff escaping the sandbox, which is pretty dangerous. I wouldn't be surprised if Discord wanted to minimize the chance of some really big problem stemming from lots of users using these unsafe versions.

The client in question here doesn't use Electron at all, so I don't think that'd be too relevant.
