It's an evil tactic, but technically they aren't doing anything wrong because they do give Silver for free. They are trying to get more sales as they know Sony is doing the Slim. Personally I don't think the strategy will work as most people who buy a PS3/360 have friends and they would tell them that it is just Silver.
It is just one of Microsofts many tactics to take sales. If Gold was free, then I would be happy, but I would still prefer PSN as it is more to my taste, but would be cool non-the-less.
