if you see carefully the strategy, you will see which one works better. Microsoft "allows" (see the quotes) to get Xbox hacked, but keep the consoles hacked out Xbox Live. My way to think is.. "ok you can have your console hacked, but if you want to play online you must be legal". Sony.. well, we all know Sony´s strategy...
What i'm trying to say is... one strategy brought more buyers than the other. Guess which one :P
