Moving of isn't easy

- thanks to GitHub pages and markdown rendering your tool's homepage is the Git{Hub|Lab|...} page. That page is linked from "everywhere" else and indexed in search engines

- all history aside from code is in there (discussions in bug issues and pull requests etc.) getting them out is possible, but all the linkage between commit messages and those might be problematic to migrate

- contributors are often only known by their handle on that page, migrating of requires new setup of permissions and mapping of usernames to trust on a social level

- there are tons of hooks configured for many projects

- as GitHub Actions and GitLab CI gain more and more traction workflows depend on those

"Just move the repo" is a fallancy which doesn't work. I have no doubts medium term about Microsoft steering GitHub, but I fear a single entity being so central in the opensoruce world (also consider npm acquisition etc.)
