For a start, you should probably read OP's article. I know often HN commenters don't read the article before commenting, and I'm sometimes guilty of this myself, but in this case the linked article offers fairly important context for my comment in the sense that it explicitly names at least one such company and gives concrete examples of what they are doing with your data.
