I get the impression you didn't bother reading the article.
Your two examples are flawed and don't address what the article is saying. The algorithm to check for copyright violations is relatively simple and dumb. Speed cameras: many countries do use speed cameras (i.e. Australia, UK). The problem with speed cameras is that once you know where they are, you simply slow down when approaching.
Again, mass vs. targeted surveillance is irrelevant now. You've already been surveilled. It's just a matter of getting access to the information.
