The two biggest problems with ECMs (real ones, not the nuisance "hashing" that merely require installation of a revised script) are: they inevitably take out some legitimate cards, and, new cards have been historically cheap by $50.00 cash and carry system purchases at Walmart. (It's not unheard of for some hackers to resign the new IRD, LNB, and dish to a dumpster!) Now that there's evidence that new systems are arriving "cardless" (to be FedEx'd only upon subscription activation), to some retailers, the easy, cheap supply of cards should start drying up. Once this becomes more widespread, another major ECM could be in the works. Such a move may be tolerable for DirecTV, even accepting the cost of replacing collaterally damaged legitimate cards, because they'd be confident that pirates would have an increasingly difficult and costly time of procuring more cards to hack.
