Exactly. The phrase 'something to hide' has become synonymous with 'something illegal' or 'you're doing something wrong', when in reality everyone has things they simply wish to keep private.
'I have something to keep private' isn't as punchy. Also it doesn't go far enough. 'My entire life is private' is closer. Of course my public interactions aren't AS private; but still largely private (its nobody's business what laundry detergent I buy at the public supermarket).
I wasn't talking about the title of the article, but in general. Those in support of these surveillance programs have worked hard to conflate 'something to hide' with 'something illegal' so that most people will go along with them as they have 'nothing illegal to hide.'
