I first heard the term on the radio today. It was an interview with Shoshana Zuboff, who coined the term and recently wrote a book on the subject. Here is an article describing surveillance capitalism. It very well may be that surveillance capitalism is a major problem, but I am not able to find any discussion of the specifics. The radio interview said that companies can build a profile of our needs and even determine our current emotional state. What kind of information are high tech companies collecting that would allow them to do this?

After buying something online, I often get advertisements for related products. That is mildly annoying, but hardly a massive invasion of my privacy. Do you have any further information on surveillance capitalism?
