The product offers the functionality of exclusion. That's not up to you, Bob, it's already there. I've included a picture for you, just in case you've forgotten.
When it doesn't work it's a bug, not some grand design.
That a bug happens to suit your fantasy that no one could possibly be any more knowledgeable than you how things work on their computer doesn't make it less a bug.
Beyond that, I've just verified and shown that the exclusion list CAN work, at least under some circumstances.
