A trial is underway involving Meta and several states. This lawsuit, expected to last about six weeks, began on Tuesday. It pits Meta against four states that are among a larger group of states that sued the tech company.

A former Meta engineering director testified that the company prioritized profits when designing its products. He claimed this approach focused on user engagement, even if it had negative effects on mental well-being.

The trial is being closely watched, with more details available from the source. A former engineering director's testimony has already shed light on the company's approach to child safety on its platforms.
