This is great and I will most likely take advantage of this new offering, but I cant help but wonder why. "everyone deserves GitHub" is marketing, not a corporate strategy. How does GitHub stand to benefit from this change? How does more non-paying users help the company? I am not trying to be a tinfoil hat jerk here. Life in the age of information has taught us all that (again) "nothing is free". So what am I paying here?
