US lawmakers wary of Zuckerberg’s Threads but about half have signed up

The latest online platform comes as Democrats and Republicans have long scrutinized Big Tech’s market power and social media companies’ data privacy and content practices. Recently, they’ve criticized tech leaders over censorship claims, misinformation, illegal activity conducted on their sites, and algorithms promoting so-called toxic content—such as eating disorders, harassment and substance abuse—to children.
