I see it more as retaining ownership some of the content we produce and happily give to twitter, youtube, facebook etc to monetise and have some more control over it
Things as being able to:
* remove access to site to display my content but still be published somewhere else if I wish to do so
* be able to serve my content to people that prefer to use another tools without relying on twitter to have a public API as long as I granted them access
* get the person getting hits and making money of ads to share some of that with me, or maybe pay my gas fees
* not be shut down because a given site or state decides my content is not worthy of it, they are still allowed to do this, but I could still continue via another "frontend" and people can choose
There are more use cases around this, and there are many gaps yet around the economics of it to make it accessible/free, make it desirable, legality, liability etc which I believe remain to be solved
