If game developers would launch their own fediverse instances (maybe with devs + moderators as the only registered users), to which general purpose instances could freely connect, then problems 2 and 3 would be solved for users as well. Imo that would be a far better solution than having game forums on a walled garden platform like discord. That still leaves the devs with problem 1, but they would also regain control of their data + the data would also be searchable with proper search engines. I can dream :)
Well put, and info hub is a great term to describe these limited purpose instances.
