“James Staten, a Forrester analyst who follows IT services, argued in a blog post Wednesday that financial losses could prove substantially higher when other market segments are considered. In calculating his higher estimate, Mr. Staten said that in addition to the $35 billion estimated by the ITIF, vendors of hosting and outsourcing services – which offer many of the same services as cloud companies, but use different processes and revenue models — could suffer an additional $100 billion in lost business. Moreover, non-U.S. cloud service providers could lose $35 billion worth of business from international customers, as awareness grows of the surveillance activities of other governments.”
