>I'm not sure what you mean, what's the "that", what do you think led to the situation where email is hard to self-host? I was referring to spam filtering, where all the big hosts know to allow each other through, but make it very difficult for smaller hosts to participate by being tight lipped about their filtering criteria and making others have to jump through lots of hoops to not be treated as spam. Which, when considering the high cost of being spam filtered (eg. if you're a business) ends up making it very hard to practically self-host. Similarly, I wouldn't think fediverse would have succeeded in the goals of federation with large centralized hosting providers. Since upon reaching critical mass, they could easily enact similar policies in the name of preventing spam or for 'safety'. The content would be going through their network and would be stored on their hardware, so they would use the same logic current social media uses to justify their right to moderate without oversight.
