I agree that there are concerns, and you would lose a lot of the depth, but my real concern is with how this makes me perceive CFAR. When I am told that there are things I can't see/hear until I pay money, it makes me feel like it's all some sort of money making scheme, and question whether the goal is actually just to teach as many people as much as possible, or just to maximize revenue. Again, let me clarify that I'm not trying to attack CFAR, I believe that they probably are an honest and good thing, but I'm trying to convey how I initially feel when I'm told that I can't get certain material until I pay money.

It's akin to my personal heuristic of never taking advice from anyone who stands to gain from my decision. Being told by people at CFAR that I can't see this material until I pay the money is the opposite of how I want to decide to attend a workshop, I instead want to see the tapes or read the raw material and decide on my own that I would benefit from being in person.
