But what about the large number of people who encounter Facebook somewhere and aren't scraping anything? After all, Facebook has no real incentive to look after the data of its users, since those data are so valuable to companies around the globe.
Menlo Park, California-based Facebook paid to buy, install and maintain security measures for Mr. Zuckerberg's personal residences, which include properties in San Francisco and Palo Alto, the filing showed.
Shares are down 16% from the all-time high that they hit before the Cambridge Analytica data scandal, which Facebook now says has affected 87 million users, first came to light.
Was your Facebook data shared with Cambridge Analytica? If true, Facebook may be subject to significant fines. "What is clear, however, is that the size Facebook has reached makes this a global issue, not just a U.S. issue".
"Facebook was not originally created to be a company".
Why do people use Facebook? "We don't claim to know what people think or feel, nor do we share an individual's personal information with advertisers". Sheryl Sandberg, Facebook's chief operating idea, floated the idea in an interview with NBC before Zuckerberg appeared in Congress.
Zuckerberg emphasized that Facebook will always offer a free version of its network.
Zuckerberg may deflect the attention of Congress, but there's no ducking the judgment of other tech executives who also rely on data to build their businesses.
Asked by Democratic Senator Patrick Leahy while he testified on Capitol Hill whether Facebook had been served subpoenas for the special counsel, Zuckerberg responded "yes", but later clarified: "I am actually not aware of a subpoena".
Zuckerberg also wasn't clear on how the company would offer all users privacy protection equal to that offered by European Union regulations taking effect next month. "And in the future, only apps we approve that agree to strict requirements will be allowed to use the Events API", said Schroepfer.
You can opt of targeted advertising by Facebook and a plethora of other advertisers using the Digital Advertising Alliance's Consumer Choice Tool or by blocking tracking cookies with browser plugins. Jefferies said in an April research note that the firm "analyzed Facebook's traffic over the course of March and believe that recent headlines around Facebook's data policies have not meaningfully impacted engagement on the platform". "That goes for data on users that click on your profile, how much time they spend on it, and what parts they mostly explore".
After Zuckerberg said he didn't know, Lujan enlightened him.
The University's School of Information has been studying the implications of Facebook and the information infrastructure for almost a decade, said information studies professor Andrew Dillon.
