If all the companies selling mining equipment are incompetent and untrustworthy, you don't have to mine. I don't any more. You don't have to daytrade either.
I never said anything suggesting that all the companies were untrustworthy. I was responding to the idea that Bitcoiners are patient - I was pointed out that wasn't the case, but that some very large players in the industry have backed their customers into corners with little way out.
