I found the following sentence on www.massimobanzi.com, near the top of the page: "Arduino users should beware of Amazon.com, they list Arduinos as provided by CanaKit (a legitimate distributor that does a great job) but when they ship they will send anything other “sellers” have listed as Arduino." Therefore, it IS Amazon that we should blame, right? The seller listed has no control over it.
I'd sure like to know who is at fault and who isn't. I live by intellectual property rights and don't want to support Amazon if - IF - they are trampling those rights. But it would be terrible to blame them for the faults of others.
