Zuckerberg said on Wednesday under questioning by U.S. Representative Ben Luján that, for security reasons, Facebook also collects “data of people who have not signed up for Facebook.”

Lawmakers and privacy advocates immediately protested the practice, with many saying Facebook needed to develop a way for non-users to find out what the company knows about them.

“We’ve got to fix that,” Representative Luján, a Democrat, told Zuckerberg, calling for such disclosure, a move that would have unclear effects on the company’s ability to target ads. Zuckerberg did not respond. On Friday Facebook said it had no plans to build such a tool.

While I don’t want Facebook to keep any records about me or my doings online, I do strongly support an open internet, which technically means that I consent to this sort of behaviour. There will always be bad actors in the world and the internet is no different. I can however attempt to block as much of Facebook as possible, by using an appropriate DNS and content blocker or host file.
