I didn't know that since I use Gmail since always but you get my point. More apps in family of apps more synergies. Here is what Google says about Google Account: "Sign in to your Google Account, and get the most out of all the Google services that you use. Your account helps you do more by personalising your Google experience and offering easy access to your most important information from anywhere." Getting back to YouTube yea tbh it would be kind of anticompetitive if Google required exclusively Gmail to use YouTube. My bad.
