This is a bit ridiculous. It's a gaming platform before anything else. In that scene it's very common to share your gaming status with others.
Not to mention that you can obviously disable this.

Hence if Discord aims at expanding its user base beyond the (multiplayer) gaming community, it should definitely think twice whether to keep this sharing setting enabled by default. At a minimum I would expect them to try to deduce somehow whether you are using Discord as a gamer or in a non-gaming-related setting, and use the suitable default. Or maybe just disable it by default, so gamers who want this feature enabled need to turn it on.
Don't worry, Discord will!
Not the same as native support, but in fairness, I was being tongue in cheek!
But you can enable it on a per-app basis.
I've known people in office settings automate their IM status (back to at least Lync/Skype for Business before Teams) to say things exactly like "making a presentation" or "busy coding", whether for fun or for micro-managing bosses or nagging coworkers hoping to digitally "peak over their shoulder".
Making it opt-out versus opt-in is maybe "gaming context-related" as Xbox and PlayStation both have opt-out versions on their own social networks. But the existence of detailed and automated status messages certainly isn't new from "gaming contexts".
