Facebook is apparently withdrawing its opposition to a California ballot measure, which is seeking to bolster consumer privacy protections. “If approved, the ballot measure would enact a new law called the California Consumer Privacy Act, which aims to enforce more transparency over data stored by companies, and give consumers a way to opt out of companies selling their data,” Variety reports.

Among other missed opportunities this week, The Atlantic’s Alexis Madrigal says Congress failed to make Mark Zuckerberg explain what data users actually own. “With Facebook, the concept of owning your data begins to verge on meaningless if it doesn’t include … all the other information that has become attached to [users’] profiles by other means,” he writes -- that “‘synthetic’ mix of actual data gathered, data purchased from outsiders, and data inferred by machine intelligence.”

Wired has compiled a list of all the things Mark Zuckerberg said he would look into during his two days on Capitol Hill this week. Among other assignments, Facebook’s CEO is tasked with finding “all the apps Facebook has banned for improperly sharing user information with third parties,” and “how many times Facebook has required audits of apps to make sure improperly transferred data was deleted."

Following Facebook’s lead, Twitter just endorsed the Honest Ads Act. As Venture Beat explains, the act is “a recently introduced piece of legislation that would require large social platforms to keep more diligent records about who is buying political advertisements." Additionally, it would require social media platforms to “make all reasonable efforts to ensure that foreign individuals and entities are not purchasing political advertisements in order to influence the American electorate.”

Instapage just raised $15 million in Series A funding from Morgan Stanley Expansion Capital, TechCrunch reports. The landing-page specialists now have more than 15,000 customers who are seeing average conversion rates above 22%, it notes. “Landing pages might not sound like the most exciting problem for a startup to tackle, but Tyson Quick, founder and CEO of Instapage, said that they’re a real issue for marketers.”

Spotify is reportedly preparing to overhaul its free music streaming service. “The redesign will reportedly focus primarily on making the Spotify mobile app easier to use,” Gizmodo reports, citing Bloomberg. “Spotify plans to make playlists more easily accessible for its non-paying users and is expected to provide more control over what songs a user hears.”

Touting Mark Zuckerberg’s strong performance on Capitol Hill on Tuesday, investors sent Facebook’s shares soaring. “The 33-year-old internet mogul managed to deflect any specific promises to support any congressional regulation of the world’s largest social media network and other U.S. internet companies,” Reuters writes. “Investors were impressed with his performance.”

To discourage platform abuses, Twitter plans to put a greater emphasis on its rules. “It sounds too simple to be effective, but it’ll be interesting to see if [participating] researchers are onto something,” The Next Web notes. “It’s entirely possible that some number of trolls aren’t aware of the effects of their abusive tweets and replies on users (while some others may indeed be looking to anger and hurt people).”

Some 20 child advocacy, privacy and consumer groups have filed a complaint asking the FTC to investigate YouTube for allegedly violating children's online privacy laws. “The groups … allege that YouTube violates COPPA, a federal law that regulates user data collection from sites with users who are under 13 years old,” CNet reports. “For [Youtube parent] Google, that could potentially mean fines levied by the FTC of up to billions of dollars.”

Thanks to iPhone X’s TrueDepth technology, Snapchat users who own the phones will now have access to some fancy new Lenses, Engadget reports. “TrueDepth-enabled Lenses appear periodically within the Snapchat carousel on iPhone X,” it notes. “They’re AR masks that follow your face around like the app’s many other Lenses, but due to the way TrueDepth works, they can look more realistic and just all around better.”
