The problem seems to be that licensing does not occur, reverse engineering does. And Canon changes the engineering unpredictably, causing heretofore working lens series to become unfunctional. If that's the scenario, who is providing the poor customer service?
They can't be changing that much, they aren't having compatability problems within their own system, that I have heard of.
