Is it a problem though? There are thousands of email providers you can choose form, and they still work fine for sending and receiving email.
On social platforms federating with everyone might not be desired and defederation is seen as a feature not a bug.
One your point on power law, the fediverse is pretty healthy.

The problem (as matrix people found out the hard way) is some media & content is very illegal. Most individuals really don’t want even the chance of being exposed to CSAM or gore, and neither do server operators want the chance of that being shared from their server or written to their disk when that can result in police at the door. You need default-on moderation that is very powerful, and end users should never be distributing media they don’t want to. This pushes towards centralisation of nodes run by experts, and heavily punishes true P2P models.

Plebbit doesn’t support media or images, only text. If a user links to an image they have to provide the URL, which is never hosted on the community owner’s node. Also, if somebody posts an illegal link or something like that the community owner can choose to purge their comment from their node.
Plebbit nodes are very cheap and easy to run, we’re very similar to Bittorrent in that regard. The next update we will have full p2p capabilities in mobile as well.
