I guess if you are Epic games, and you do not want to be blocked or controlled by App Stores, or pay 30% paycut. maybe you would build and support independent (from google/apple monopoly) interenet stack.

or if you are EU/China and do not want google DNS and networkign layer owning entire EU/China

in all cases they would still want centralized control by each state/company.

how to align incentives of someone who can actually pull this off and still keep it decentralized is a big question.
