Perhaps it's only been since lately that this issue has really taken off, that MS decided they would like to see the adapters in question.
You know, at first it was only a few, but then it became a lot more and was suddenly on Microsoft's radar. Then just the last day or two decided to try to recall the defective adapters.
Maybe when it was indicated by those reporting the issue to Microsoft, and them getting a replacement without having to send it back or provide a picture proof, we might have gotten a rash of opportunists trying to cash on the liberal policy. Just a thought.
