Unfortunately they denied my application when I tried to get one during my college years.
I felt envy seeing some my peers (who had no existing repos, or far fewer than me) get free PRO accounts while github probably though I should just buy one.
Long story short, I created a bitbucket account and later made heavy use of gitlab.
Love seeing that! Maybe, just maybe, they do that to enable the Da Vinci example given in the article? Students that might be creating the next Facebook-like company in their dorm? Who knows
