Preatoni is the founder of Wabisabilabi, a Switzerland-based company that bills itself as an auction site for the software bugs that companies like Microsoft never want anybody to see. He spoke at Microsoft in late September as an invited guest at Microsoft's semi-annual

Blue Hat security conference.

But what had been an edgy invite by Microsoft's Blue Hat planners took on a new dimension this week, when Preatoni was arrested in Milan on charges relating to a national spying scandal at Telecom Italia, Italy's largest telephone carrier.
