@miauw @Gargron It literally can't be sold.
The fediverse isn't one website. It's thousands of websites with millions of users, operating on dozens of separate software projects, all having the ActivityPub federation protocol in common.
You can no more purchase such a thing than you can purchase "The Internet". It just isn't a thing that's for sale.
We've had different parts of the fediverse decide to "go private" and stop being part of the broader whole (and websites based on open source software that nonetheless disable activitypub support and federation from day 1), and it just means people have to move to different instances that still properly federate.
That being said, it's a two sided sword: on one hand, no one person controls it so it can't be sold. On the other, no one person controls it so if you're expecting unified moderation (and the possibility of influencing that moderation) beyond the instance you're presently on, you're out of luck. Each instance is a unique website run by its own admins, so moderation decisions are limited to either content on the specific website, or the import of content from other websites (and possibly the export of content to the same other websites).
