I favor transparency, with the goal of educating players. But phrases like "transparency" and "scamming" imply that it's all the player's money, from start to finish.
Anywhere else where I pay admission or pay to participate in an event, I don't expect a financial statement to demonstrate where my money went. I judge whether the concert or amusement park or guided canoe trip was worth what I paid, in terms of enjoyment. If it wasn't, I don't go back.
I feel the same way about disc golf tournaments. If I pay $40 to play and get $40 enjoyment for a weekend of participation in an organized event, I'm happy. I don't particularly care about the financials, except that I hope the TD didn't lose money on the deal.
