They never said they continued to patronize Amazon. Given the thread kicked off with claims about loosing access to DRMed content due to an unrelated delivery/payment issue, the person involved may be concerned about loosing access to digital content. Some people spend a lot of money on books, movies, etc.. The $1000 may be a drop in the bucket.
> I could chargeback my credit card but I imagine I'd also be permanently banned from Amazon - so instead I accept they've just stolen $1000 from me with no recourse...
To some this could imply they wanted to continue doing business with Amazon, so accepted the theft. Not losing access is, in a way, continuing to do business. Not sure if that's what they meant, but I can see it being interpreted as such.
