Not sure about you guys, but I buy products not to "stick it to the man," but because they do something I want or need. And as an Apple stockholder since 1989, I am all about them MAKING MONEY. I think that's the point, actually. Otherwise, you are a non-profit....
As for locking in with AT&T, they seemed to be the only large wireless provider willing to change/implement technology that the iPhone required (namely for visual voicemail). Verizon passed on the opportunity.
It seems everyone thinks that technology should be free or unlocked. Not sure why people are upset that a company has created a product, and chooses to offer it as it pleases. It's their loss if they are limiting potential customers, right? (not that this is a good thing, but I can understand why AT&T wanted an exclusive for the first two years. If they put $$$ into infrastructure, then they want a chance to make that back)
