That's a laugh. When does Apple back down from defending itself?There has been no evidence that Apple ever provided Siri recordings or information from Siri recordings to advertisers, and Apple's privacy policies have long made it clear that any data collected from Siri for the purpose of improving the feature is anonymized and not associated with a specific user.
In the settlement filing, Apple says that it "continues to deny any and all alleged wrongdoing and liability, specifically denies each of the Plaintiffs' contentions and claims, and continues to deny that the Plaintiffs' claims and allegations would be suitable for class action status." Apple is settling to avoid further costs of litigation.
Could the real reason for why Apple is settling be that Apple doesn't want it to get out that Apple was selling user data to advertisers? This would be revealed if the case went to trial during the discovery phase as Apple would have to turn over such data.
