Honestly I see the fediverse as a massive opportunity for corporations.

If you're Google, why not host a Google corporate instance where everything is authenticated as your own content, under your own URL, but you can still reshare outside content? You'll never have the issues of unwanted or controversial content appearing with your brand. There's no chance of a parody account pretending to be your customer service, and you won't have to pay a protection fee for an authentic checkmark.

This is 10x more important for governments to do, as right now I can't view official political discourse from my own government without giving my data to a private company.
