Well whaddya know... the Electronic Freedom Foundation agrees with me.

Most companies offer privacy settings, and some even let you leave and take your data with you. But they don't make it easy, and critics say social networks and internet companies should give users far more say about which data ends up in advertisers' hands -- and when.

"Tech companies can and should do more to protect users, including giving users far more control over what data is collected and how that data is used," said the Electronic Freedom Foundation in a statement. "That starts with meaningful transparency."

Once you share something on any digital service, your personal information leaves your control. Cambridge Analytica serves as a stark reminder of that.
