It certainly raises some interesting questions about developer anonymity and whether the trustworthiness of an individual has bearing on the code they produce. Would people feel differently about Bitcoin if Satoshi was ever identified and had made questionable decisions on any previous projects they might have been involved with? It seems clear that something as groundbreaking as Bitcoin couldn't possibly have been someone's first rodeo, so it's likely that some errors were made on the journey to get there, we just may never know what they might have been. Therefore, would we be treating ETH differently if Vitalik had never revealed his public persona to the world? And does any prior transgression detract from what is now peer-reviewed code in the wild?
It is quite funny sometimes how we usually shout praises for somebody of his accomplishment and when there are no more areas of that person we like to talk about, we go and scrutinize that person's past errors. This is also an approach popularized even by the mainstream media...like a love and hate relationship. We praise and then we surgically scrutinize.
Now, having said that, we have to realize that nobody is perfect. Steve Jobs was a great man but he had his share of failures and mistakes too. Expecting somebody to look and feel like an angel can be beyond comprehension. Maybe it is enough that somebody made a great contribution for the advancement of humanity.
Entrepreneurs are humans too and there is actually that tendency to get into failures before seeing some success. While there is nothing wrong to resurrect someone's past in light of how we have this tendency to scrutinize others more then we do ourselves, it should be made as an inspiration that somebody, despite some failures, decided to continue his journey for success.
