Here's the problem with cryptonote: if I play 10 hands of poker at an online casino, with money I bought on an exchange, I have very little privacy. Anyone who can coerce or compel the casino and exchange's cooperation can get my real identity simply by looking at intersections amongst potential ancestor payments. This is because in cryptonote, each payment only has e.g. 4 potential ancestors. While each of those themselves have the same property, you can still look at intersections and deduce linkages with very high probability.
