To be fair, I seriously doubt the OP is a casino spy, and I also don't think that JG is very worried about the book getting into the hands of those cunning and dangerous casino folk. The real threat to the game is in the form of unscrupulous rookies that are in such a hurry to make advanced plays that they forget the most important aspect of playing the games, which is not burning them out. An unfortunate result is that many honest, intelligent players will not be able to gain access to the material, but I feel it's very likely that motivated individuals will make friends at some point in their career if they continue along this particular path.
However, since JG is clearly not motivated by book sales, I really wish he would make some of the material public (a la Beyond Coupons), possibly in a revised form that omits sensitive material and focuses on metagame considerations. There is quite a bit of material in the early pages of the book that would greatly benefit the beginner, without covering sensitive topics.
