A coalition of state attorneys general is launching an investigation into how Instagram, owned by Meta, draws in young users and affects their well-being, some of the states involved announced Thursday.

Why it matters: Meta has made it clear it wants to entice young users in order to compete with companies that have been more popular with kids and teenagers, like TikTok and Snapchat.

Facebook on Thursday said it is expanding the controls it gives advertisers to make it easier for them to limit the types of News Feed content their ads show up next to. Excludable categories include news and politics, tragedy and conflict and debated social issues.

Ohio attorney general Dave Yost filed suit against Facebook parent company Meta, alleging it misled the public about the potential harm its products can cause.

What's happening: Yost filed the lawsuit on behalf of the Ohio Public Employees Retirement System (OPERS) and Facebook investors, citing the Wall Street Journal's reporting and internal documents leaked by former employee Frances Haugen, according to a release from Yost's office on Monday.

Why it matters: It's the latest legal salvo against Meta, which is facing multiple federal, state and international investigations. This one comes on the heels of Haugen testifying to a U.S. Senate subcommittee and the European Parliament about Facebook's internal research and decision-making.

• Facebook knowingly made false statements about the safety, security and privacy of its platforms, the suit, filed Friday, argues. It says those revelations caused Facebook's stock to lose value, costing the investors and OPERS more than $100 billion.

What they're saying: "Facebook said it was looking out for our children and weeding out online trolls, but in reality was creating misery and divisiveness for profit," Yost said in the release. "We are not people to Mark Zuckerberg, we are the product and we are being used against each other out of greed."

• The suit seeks to recover the lost stock value and demands Facebook make changes to guarantee it does not mislead the public.
• A spokesman for Meta said the suit is "without merit" and that the company will defend itself "vigorously," per CNBC.

While legislators and regulators around the world weigh big changes to Apple's and Google's app stores, some quick revisions could be coming within weeks, thanks to a U.S. judge's decision and a Korean law.

Public like and dislike counts, once a baseline offering for social media companies, are disappearing as tech platforms begin to uncover ways they are being abused.

Why it matters: Engagement mechanisms such as "likes" or "reactions" make tech platforms stickier, which is good for selling ads. But they're also becoming a risk factor for tech firms that are under pressure to address issues like user wellbeing and misinformation.
