Required github login? Not everybody uses github, it's a very big world when internal AI and Eng corp groups span the globe.
The target audience for this is college kids, who these days frequently use GitHub for consuming course material (e.g. boilerplate for class assignments). Doesn't seem like a bad move on their part to avoid rolling their own account system. People like one-click auth.
Yeah, but they may not have an account on github.
And I see more and more students using gitlab instead since they have free private repos
