Privacy and corporate giants

Focus on privacy and corporate giants. Feel free to call your paper what you wish.
A simple search will reveal a great deal of concern with respect large corporate entities in the tech realm and the privacy of individuals. To get a sense of this concern, peruse a few links resulting from a search such as “what does Google and Facebook really know about me?”
Write a paper that attempts to answers this question and more. Consider some of the following questions:
 Are there other corporate entities that are of concern, but tend to go unnoticed?
 Are we too fearful of the likes of Facebook and Google?
 Is privacy as we know it dead or perhaps no longer a social norm (credits to McNealy and Zuckerberg)?
 Is the public really that concerned over privacy?
 What might the future hold?
 What is the Canadian perspective?
 What is your personal perspective?
