Why are cloud and consumers criteria at all? That's why this list feels like such an odd mix - there shouldn't have to be anyone from the cloud, if they don't make the cut weighed against everything else in the entire world then do a separate list on innovation in the cloud where they can be recognized for their achievements without compromise.
Those aren't criteria, but the fact that they have designed so-called cloud storage in a useful way that is accessible to the masses is why they were included on the list. I also think that it is important that a cloud company be included in the list. So I wonder why you think there shouldn't have been anyone from the cloud?
I don't think the cloud specifically should be excluded or even a factor in and of itself, I think the most innovative companies in the world are by definition the ones who are innovating the most, cloud or otherwise.
Twitter belongs on the suspect list too, how can they still be one of the most innovative companies in the world for a product largely unchanged in 5 years, during which time a jaw bone was printed and transplanted into a person?
