It also makes it very difficult to censor. There is 1 YouTube and thousands of ActivityPub servers and relays that would happily carry all posts through the fediverse regardless if they seize one or two hosts. There are other options as well - that was a bit my point that Medium/X/Bluesky/YouTube - these are designed to harvest engagement in exchange for content. They’re not good for news and certainly not good as an archive.
In theory yes, but in practice, most of the traffic will gravitate to popular servers and the popular ones will be targeted by people that want to censor content and force the gatekeepers to silence content. The ones that don't play along wont matter because they are not that visible.
