I can definitely see why companies would be interested in this. Near total control of content and the resources behind them? Don't have to worry about being tied to bad publicity of a specific platform?

Of course this is wide open for them to abuse this by restricting content to only what they want, but the nice thing about the fediverse is that it would likely just be one of many resources for content on that topic.

I don't see many people wanting to create their accounts with such an instance, but definitely could be nice as an "official" source of news. Could one day likely replace official forums on company sites as it essentially fills the same use case but is federated so its content reaches larger audiences.
