It's meant to be bigger than just Splinterlands and the SPS DAO. We're actually looking to onboard other projects to help make this initiative bigger. As far as the account ownership. The SPS DAO owns the account and it would be turned over if the SPS DAO chose someone else to manage it. Feel free to follow the account or don't, the posts asking for DAO approval of projects will be shown in game and should provide an alert that a new proposal is available if you'd like to check it out.
