You're missing the point. The point isn't that the hypothetical banker can't have an active github profile, it's that there are reasons they might not. Take me for instance, I haven't really done anything significant in the public for over a decade now. The vast majority of my code has been for one private company or another. And that's the case because either my job has me working the hours or after putting in 8 to 10 hours of code in private, there's exercising, practicing guitar, socializing with friends and family, building Lego sets, reading, playing video games, and other activities that don't involve me writing more code. That's not to say I don't, it's just I don't have that much time to do it outside of work.
