Let's get real. If a billionaire comes in and buys #Bluesky, the 30 million users who have fled there from other toxic platforms will be stuck on the billionaire Bluesky toxic platform. Sure, they can "fork off" and make a Mastodon account on the Fediverse, but that's their only option.
This 'billionaire proof' marketing campaign of hers is not only disingenuous, it is false advertising, and should give everyone pause.
