Some people get offended when for-profit companies turn out to be not neighborly or friendly or human beings.
I like to look at it from the perspective that they are a for-profit public company and are legally required to maximize shareholder value, and they have every right to do so.
Therefore, any plans I make regarding GitHub will not rely on them being friendly and kind-spirited in any way. If they turn out to be great, I'll just be pleasantly surprised.
