Superbloom:
The combination of deregulation and digitization erased the legal and ethical distinction between interpersonal communication and broadcast communication that had governed media in the twentieth century. When Google introduced its Gmail service in 2004, it announced, with an almost imperial air of entitlement, that it would scan the contents of all messages and use the resulting data for any purpose it wanted. Our new mailman would read all our mail. The public, in thrall to Google and eager for free email accounts, barely flinched. The centuries-old secrecy-of-correspondence doctrine was tossed aside just as personal correspondence and conversation were moving online. On the internet, the wiretap wouldn't be a bug; it would be a feature.
A change of context is all you need to confuse people out of their rights.
