A Stanford study reveals that a potential divestiture of Instagram from Meta would increase competition among advertisers but ultimately harm users by exposing them to more ads. The research suggests that while ad prices may decrease, the quality of user experience could diminish as Instagram would need to target users more aggressively to compete with Facebook. The findings pose challenges for the FTC's case against Meta, which argues that the company is a monopolist.

Google is in the final phase of an antitrust case focusing on its dominance in digital advertising. U.S. District Judge Leonie Brinkema is evaluating potential remedies to enhance competition in the ad tech market, following earlier rulings that found Google had illegally monopolized online auction technology.
