AppLovin sues Unity over alleged data collection through its Ad Quality SDK
AppLovin sued Unity in California court, alleging data collection via Unity's Ad Quality SDK without permission. AppLovin claims Unity used this data to train models for ad auctions. Unity denies the claims, calling them anticompetitive. AppLovin seeks a temporary restraining order to halt data collection and modification of the SDK.
