do you think Yahoo, Google and like need a good shaking to stop them from interfering with our computer internet experience, and how to go about doing that shaking?

Computer technology follows everyone everywhere on the internet and maybe we don't want the choices they make for us, but new and additional choices aren't allowed to us or given to us so that we can expand our horizons. So how can we get thru to the thick headed Yahoo, Google, FB, Microsoft and the like?
Example: If I write on a specific subject in either YA or in a Yahoo email, up pops an ad in my email on that subject. While it can go to my spam folder, I dislike it that this form of automation is so pushy so asked the question, how can we as a group tell these companies that we want to see different things and not just what they think we want to see.
