Texas Attorney General Ken Paxton on Monday filed a lawsuit against streaming giant Netflix, accusing the company of illegally collecting and monetizing personal data from users, including children, in what he described as a “behavioral-surveillance program of staggering scale.”

The lawsuit, filed in Collin County state court near Dallas, alleges Netflix misled consumers for years by portraying itself as a privacy-conscious, ad-free alternative to major technology platforms while secretly tracking detailed behavioral information about users and sharing it with data brokers and advertising technology companies.
