It's mind-blowing to realize just how much git and github have changed my expectations:
This is a protracted, bitter discussion about whether it would be ok to CREATE A BRANCH.
I was thinking this too. If they were using git you wouldn't have to ask for permission or have the ability to deny it. They would just make a fork then their own branch and submit pull requests if they see fit.
IMO, the current title unfairly sensationalizes the (what seems to be a very reasonable) response, and is a good example of why "editorialized" titles are ought to be discouraged.
