Wow, that's vicious. How about this for a chain of events.
AMT takes responsibility for making poor choices in the fulfillment of it's processes and issues a recall.
AMT issues this recall of miners (even though some still work fine which has been noted here several times by several members) in order to insure that clients get long lasting working products, and AMT re-builds and reships all miners that were previously shipped out, while scrapping the returns.
I'm not hearing anything about compensation for delivering 6 months late. You really should clarify your plan.
