I'd really love for that happen, but I would advise people to not get their hopes up.
In order for you what you're saying to be correct, then you would have to accept that someone who is very familiar with cryptocurrency and is smart/sophisticated enough to build an exchange is also too dumb/incompetent to understand the repercussions of letting the exchange stay down for this long with zero communication - repercussions in terms of his business reputation, his personal reputation, and the fact there are some people out there who might go after him. Not to mention, he makes money off of people trading on his exchange. If he is honest, he's really hurting his business beyond just the trading fees he'll miss out on while the exchange is down. He will lose current customers over this and potential customers will avoid his exchange. There is no way that he wouldn't understand all of these things.
All that being said, it seem that there's a very good chance that he's dishonest.
