Another instance of this is Urbit. I wish it didn't use ETH for namespace but it is a pragmatic solution and funds development, the rest of the architecture is free of blockchains. I especially like the model of moving your "ship" from one "pier" to another if you don't like the moderation, tho the network hasn't really gotten big enough to actually experience a netsplit like mastodon - it's a couple thousand users if that. The fact that a 32bit name costs money adds a bit of a durable reputation factor, but 128bit names are free.
