What open standard? Email? Github doesn't change git, it changes the workflows around it.

Even if everyone used github, they're still using vanilla git underneath.

In a similar way you could argue that git doesn’t change diff and patch. It just adds a a convenient way to handle patch files. So why open source it? It turns out it’s very useful to have it in software.

The same is true for tracking forks and managing pull requests.
