Not really. Your GitHub account doesn't belong to you: it belongs to Microsoft. They let you use it as long as it pleases them, but it's their database and their servers and they don't have any obligation to continue to do so.

Use Gitea instead. It's great and doesn't add eyeballs to this giant corporate SPOF. It even has a feature to push everything in your repo to a remote (eg GitHub) as a mirror automatically. (Or set up a repo as an automatically pulled mirror for the inverse.)
