While that's a common conflation I don't think the GP was doing that. While I tend to self-host git, I can see the value they're claiming fossil has.

Whether self-hosted git or hosting on Github, your issue trackers and such are typically separate from your main repository. Most platforms offer wikis as a side-by-side repository so that should be easy to move, but the rest is at the whims of the platform.

The GP is claiming they moved to fossil because the one repository contains all of this data.
