I agree with everything, but the "free" part. Haven't we all heard the saying, "you get what you pay for?" The best textbook I know about is Campbell's Biology. It was written by tons of experts in the field. Did they all volunteer to write it? Shouldn't experts be compensated for their time in the creation of quality textbook content? I know we would all like everything to be free, but writing (or producing audio or video) GOOD content takes skill and expertise. Are all these people supposed to do this for free? I just don't understand the idea behind this.
