Github community in turmoil after hacker exposes massive security flaw

Github, the service that many professional programmers use to store their work and collaborate on coding, was hacked over the weekend. A young Russian named Egor Homakov showcased a loophole in Github that would allow anyone to commit to the master copy of a project, meaning they could alter or delete the source code. But when his account was suspended by Github, a furious argument broke among developers out about his intentions. Was he doing the community a service by exposing the flaw or taking things too far with a very public hack?
