The situation with GitHub has radically changed, it is no longer a neutral and independent project which exists solely to provide a service to entire developer community. It is now a tool to leverage more profits for one software company — a company who has proven they care much more about market dominance than the wider tech ecosystem.
I’m not trying to imply some forgone conclusion that GitHub is doomed or that ms will ruin it, but the entire purpose of the project is now completely different than when it was an independent company and we would be wise to keep this in mind.
I particularly think we should be watching and cautious to see what types of changes they try to leverage into git itself.
