Even Zuckerberg doesn't seem to know, he appears to have lost control of what's going on. Unfortunately, the hearing didn't dive into details to better demonstrate that he can't tell why somebody sees what they see, and who uses the data (inside and outside of Facebook). Also, the whole collecting data "for security purposes" is pretty unbelievable. Does that mean they share information with governments around the world? This can be interpreted as anything.
