@evan great question. I think: build resources for groups that want to govern (like the IFTAS library does for moderation), build tools for governance (third party and supporting PRs to major software, again kinda like IFTAS here), and advocate as necessary in standards groups for the needs of groups that want to self govern (just like.... okay these parentheticals are getting repetitive)
@darius So, I get that, but I think it's more likely that we'd see advocacy for particular governance structures. Say, a Federation of University Social Networks, which focuses on the needs of those kinds of instances, and a different Alliance of Cooperative Social Platforms, and so on. Unsupported crystal ball prediction; take it for what it's worth.
