Congrats on the launch. This seems very compelling. For anyone asking "Why can't GitHub just do this?", (1) never underestimate an extremely smart and motivated team, and (2) competition is critical and valuable.

Let's celebrate when teams build products to fill big needs, instead of dismissing things because of a potential threat from a big company. If we dismiss new things, then we'll just end up in a world where big companies get complacent and devs get less new stuff.
