+Obviously nothing prevents OSS users from replacing this topology with their own, changing the hard coded topology signing identity and update URL in Defaults, and signing their own dictionary. But doing so would yield a network that would have a tough(ish) time talking to the main one. Since the main network is a free service, why bother?

-Increasing decentralization via federation or trust network is possible in the future though, provided it can be done without sacrificing stability, security, performance, or ease of use.
