Github has been requiring authentication now for "untrusted" ip addresses. They also have aggressive rate limits such that a business running build server(s) will likely hit rate limits.
The reason that's a big deal is, many, even more commercial funded OSS projects, publish their artifacts exclusively on GitHub releases, or the GH container registry. Powershell is an example of this. They're not only locking down development, but also the public's access to the applications entirely. It's total control over software development and distribution.
nostr:npub1s3ht77dq4zqnya8vjun5jp3p44pr794ru36d0ltxu65chljw8xjqd975wz plans to help with this, but we aren't going to be an end-all solution. No single SaaS platform will be.
Devs should consider running their own git servers and artifact repositories for their projects. Other self-hosters and plebs can contribute by setting up git mirrors on just about any webserver. Mirror projects you care about!
Devs should also probably be signing their commits so that mirrors can be verified.
Final note. CodeBerg offers a GitHub 1 click repo migration tool.
