I don’t have a Github account after deleting it some time after it was ought by Microsoft. Given the rise of anti-US sentiment and calls to stop using their products, more people leaving Github might be a real occurrence. How can I and others who have left, are leaving, and will leave Github, be able to contribute?
You can’t. Even if there are mirrors elsewhere, you have to use github at least indirectly to contribute to the source
Highly unlikely. Github has nothing to do with current politics and has massive network effect. There is no way in heaven or hell you’ll see much effect on Github from this
