Strategy article "Cheaters in Poker Never Win"

This is an interesting article - Poker Cheaters Never Win - Poker Story. If you've read it, tell me what you think of my initial response to it, which was, yeah, the house was cheating and yay they got caught...but the author text-messaged his friend during the game to tell him about a player's tell that he'd thought he'd seen. This was before they realized the house was cheating. Isn't that cheating, too - tipping off another player about someone's tell?

I do not consider sharing that kind of information cheating; and the article was kind of interesting.
