He didn't. His personal bankruptcy was annulled.
But even if he did go bankrupt from the CoastJet business failing, should that be broadcast to everyone as soon as they even type in his name into Google? It's completely out of context. He didn't go bankrupt from being sued by patients. He didn't go bankrupt by gambling his money at the casino (although buying into aviation at this stage of the game could be argued as riskier) - the guy is being punished needlessly.
Does this have to go to a lawsuit though? Why can't Google seem to moderate themselves effectively? You should be able to fill out a form saying "Google autocomplete is being mean to me" and Google decides whether or not it makes sense to remove said autocomplete. It shouldn't be hard. Simple common sense.
I don't know what the case here is, but if he did try to contact Google then I'm sure they ignored him completely as they are wont to do.
Anyone who claims this is about freedom of speech are being ridiculous. Should people be able to buy billboard space around the world and declare to the world that you are pedophile? Or something true, a compulsive masturbator? What makes a Google autocomplete any different?
