Apple is one of the worst companies when it comes to user privacy. They share everything, including your voice. You think that talking to Siri is personal and safe but it is not. The company admitted that they share audio collected by Siri to 3rd party companies (yes, more than one) and they do it for at least two years. Even if you trust Apple with your privacy, I can’t even imagine what you asked Siri about, can you really trust every 3rd party company and their employees? I don’t think so. If you believe that whatever you said to Siri isn’t confidential then think also about every email or sms you sent by using your voice (speech-to-text). Now, go buy also their watch like a nice brainwashed human being you are!
