I don't think Verizon is "punishing" Samsung for anything. There's a far more obvious, and business-oriented answer. When it comes to Android devices, Verizon likes to advertise their Droid line over non-Droid branded devices. With the Note 2, like the Galaxy S III, the device isn't a part of the Droid line, and more importantly it's not a Verizon exclusive. Most importantly, the Note 2, like the S III, is available (or will be available) on all major U.S. carriers. Verizon would rather market exclusive devices, because by marketing those, they're also marketing the fact that you have to be a Verizon customer. The same doesn't hold true if they heavily advertise or put a lot of emphasis behind devices that are available on every carrier.
So, is Verizon holding back the Note 2's release because of the DNA? That's very likely a part of it. But it's not because they're trying to punish anyone. They want to give their exclusive devices most of the exposure, along with a head start, because if someone wants of those, they have to be on Verizon. It just makes more business sense to put an emphasis on exclusive devices when it comes to marketing and release, especially when Samsung is already doing more marketing for the Note 2 than Verizon does for pretty much any device (as they also did with the S III).
