Indeed, information about HFT is slowly starting to leak into the open. This has historically happened with every new profitable trading strategy. It starts with one company doing it, then a few, then a lot (there's money in it), and then someone publishes an article about it and the cat is out of the bag. Slowly after becoming public the strategy becomes less and less profitable (more people get into the game). With systems like this, it's all about the information asymmetry.

Yeah, it is getting out and I think current press stems for some recent court cases. It's also not a new strategy - with at least 6-7 years in practice by most competitive hedge funds. If you studied non-linear mathematics, or genetic algorithms in the early 2000s, you would have seen a ton of journal articles on the subject, particularly involving currency trading.
