I think a properly decentralized system (basically everything Github was except stored inside or alongside the repo) solves the self-hosting headaches also -- If everyone has the issue queue, kanban board, yadda, CI results, etc. on their laptops you don't have to host and administer some app to do any of those things, only a dumb storage for backup and sync and services like CI that support those things in any kind of centralized way -- all of which you can still pay someone else to do for you.
