Unfortunately, you've probably explicitly agreed otherwise numerous times when you've affirmatively agreed to various Terms of Service agreements for all sorts of online services. As I see it, the problem is a combination of weak privacy laws and lack of compelling, affordable, and easy to use paid alternatives for a lot of digital communication services. This is exacerbated by social network effects where you can't easily opt out of speaking with your family/friends online since they all happen to be on services that harvest your data. You don't have to join, but you miss out on a lot of digital communication with your own network, which is pretty lame.t is my position that my personal data is proprietary. I own it. It is mine.
Period. I've never given permission for anyone to harvest my habits.
