I think you have a good point. A rich man, (any man?), would go to the lawyers, he wouldn't just go and close a semi successful site because his son made a bad business decision. I think the costs of running the site proved a little too much for his limited budget/knowledge. FFMG
So the reason is personal. Something that involves the interest of his father. Oh well, I think surch is still gonna be back within the next couple of days. It's too good to just throw away.
I could be wrong: But wasn't this the same guy who said he had spent thousands in development and then got caught out for using a standard SE script.
