Meta stock ends lower as New York warning-label law and teen-user leak renew scrutiny
Meta shares closed down 0.7% at $663.29 on Friday as New York enacted a law requiring mental-health warning labels on social media platforms with features like infinite scroll and autoplay. The law allows civil penalties up to $5,000 per violation and targets algorithmic feeds. Instagram internal documents show efforts to win back teen users amid mounting lawsuits and oversight.
