It's not the users choosing to share something that's the problem, it's the corporations choosing to collect every bit of data on their users they can without the consent of the users. From the article:
> "But it gets worse. These social media giants are collecting data about every single internet user at an alarming rate, housing it in enormous data storage facilities around the world. Once collected, this information is analyzed, compiled, and sold to any interested parties willing to pay for it. It’s not only your activities in a web browser that are gathered; many smart devices including televisions, smart phones, home automation equipment, and more will passively listen to casual conversation looking for key words and phrases. This data will be correlated with the online profile of the speaker with speech recognition and anything you talk about will be added to a database of your interests. Once complied, this data becomes impossible to track down and remove. A user’s personal data will never disappear from the internet. It will be continually be added to, recompiled, reanalyzed, and sold over and over in order to sell ads in the hope of selling a product. If you sign up for a free service on the web, then you are what is being sold."
