Is Discord safe from Cybersec perspective?

Sup everyone. So recently I found out that Garuda Linux doesn't have it's own Discord server and there was a whole novel as a reason why not. And one of the reasons why they don't want a Discord server was "Discord is proprietary, bloated and insecure. Yeah, it's convenient, and it's settings are robust, but our users and developers don't want to be hacked".
So my question is, any of you know how Discord might be insecure?
