Earlier quoted context omitted.
Providing a demo - great. But why all the complaints about requiring third-party login? It wasn't so long ago we were all complaining about "yet another account" and asking sites to support third-party logins.
That's not what he means and you know it. They require Social connect without a demo or any substantive reason to do so.
As far as social connect - it's using the most popular authentication service (Facebook, where you can usually control any social permissions), and a dev-specific auth service (GitHub). Sounds a lot better to me than creating a new account somewhere else, particularly as I trust those two providers with authentication.
