The article disputes your second point: But in March, 2008, before fleeing Geneva, he had sent e-mails to British and German intelligence agencies, announcing, “I have the whole list of clients of one of the world’s top five private banks.” (The agencies did not pursue this opportunity.) He also contacted a French revenue inspector named Jean-Patrick Martini. During the summer of 2008, Falciani arranged a secret meeting with Martini in a French village across the Swiss border. Martini brought along a psychologist, who helped him come to the conclusion that Falciani seemed credible about the provenance of his data. (he fled Geneva in late 2008) The fact that the Swiss convicted him of industrial espionage when the main point of the article is how important bank secrecy (and it's protection of tax evasion) to the Swiss shouldn't really help anything.
