All well and good. Let me tell you what doesn't fly here. Making threatening remarks and naming vendors without 100 percent concrete evidence, which is very difficult difficult to obtain.
You would do well to remember it.
I agree with you, and I highly doubt it was a specific vendor. My bank doesn't even seem to particularly believe that it was the numbers directly being stolen. They seemed to feel there was a good chance it was someone running number generators, which have apparently gotten more sophisticated and easier to obtain....leading to a lot more people doing it leading to a higher statistical likelihood that you'll get hit. I think the onus is going to fall more squarely on banks to make come up with ways to make our cards more secure; apparently some already have passwords required on their cards even for online spending, and I would love to see mine do it, too.
I do wonder, though, if there is any way to determine whether it is any one "shopping cart" platform that is having the problem.
