edit: why do people vote me down when what I say is true? I'm sorry but I'm not willing to pay for tutorials on open source applications that I can otherwise legally get for free. Humble Bundle isn't even a non-profit corporation. They are a private for-profit corporation where profit is the bottom line and donations to charity are more of a marketing gimmick used to reach that bottom line. Humble Bundle is a highly, highly profitable middle man operation that banks on the altruism of people.
