The second season of Iron Blooded Orphans is a good follow-up to the first, and certainly contains the themes you’re looking for.

For what it’s worth: I self-host gitea, and it gives me the possibility to import not only repos but also issues, projects, etc from GitHub, gitlab, bit bucket, and a handful of others.

I don’t know if Utterances can work with gitea’s API. If it does, then in theory you should be able to migrate to gitea from GitHub for this use case.
