During his testimony before Congress on Tuesday and Wednesday, Facebook CEO Mark Zuckerberg has repeatedly suggested that Facebook users have complete control over the information they share with Facebook.
But it's much more complicated than what he implies.
Here's an example of a talking point Zuckerberg has been repeating in various forms:

"Every single time that you share something on Facebook or one of our services, right there is a control in line where you control who you want to share with."
