WhatsApp隐私政策重大调整：与Facebook共享数据引发安全担忧
2014年，当Facebook以190亿美元天价收购WhatsApp时，联合创始人Jan Koum曾承诺用户隐私不会受到影响。然而本周四，WhatsApp宣布了四年来首次重大隐私政策调整，将开始与母公司Facebook共享用户数据。
In 2014, when Facebook acquired WhatsApp for $19 billion, co-founder Jan Koum promised user privacy would remain unaffected. However, this Thursday WhatsApp announced its first major privacy policy update in four years, beginning to share user data with parent company Facebook.
此次政策调整的核心内容包括：
The key changes include:
- WhatsApp将分享用户电话号码等数据给Facebook
- WhatsApp will share user phone numbers and other data with Facebook
- Facebook将利用这些数据进行精准广告投放
- Facebook will use this data for targeted advertising
- 企业可直接向用户发送营销信息
- Businesses can send marketing messages directly to users
WhatsApp一直以其"端到端"加密技术著称，连平台自身都无法读取用户通讯内容。但这次调整意味着用户数据将首次被用于商业目的。
WhatsApp has been famous for its "end-to-end" encryption technology, where even the platform itself cannot read user communications. But this update means user data will be used for commercial purposes for the first time.
WhatsApp解释称，数据共享将帮助：
WhatsApp explained that data sharing will help:
- 改善好友推荐系统
- Improve friend recommendation system
- 过滤垃圾信息
- Filter spam messages
- 展示更相关的广告
- Show more relevant ads
然而，这一决定引发了用户对隐私安全的担忧。WhatsApp曾因拒绝向FBI提供用户数据而对簿公堂，如今却为Facebook打开了后门。
However, this decision has raised concerns about privacy security. WhatsApp once went to court for refusing to provide user data to the FBI, but now it's opening a backdoor for Facebook.
专家分析：这是WhatsApp商业化的第一步，Facebook终于开始将这笔190亿美元的投资变现。但如何在商业利益和用户隐私之间取得平衡，将成为WhatsApp面临的最大挑战。
Expert analysis: This is the first step in WhatsApp's commercialization, with Facebook finally beginning to monetize its $19 billion investment. But balancing business interests with user privacy will be WhatsApp's biggest challenge.
