This was my thought as well. It makes sense for companies to setup their own Fediverse instances. It provides them a way to reach their customers without having to rely on another company acting as the middleman.

Mastodon is really solid and with the Dutch government and the BBC running their own instance I imagine others will follow suite.

Still not sure about a Reddit replacement though since both Lemmy and kBin have their problems.

Spin up a PeerTube instance and companies have an effective means of setting up discussion forums for their products, a news feed for broadcasting updates, and a video hosting solution that can all be tied together through the Fediverse.
