当广告客户将任一用户添加到其目标客户匹配名单中之后，该用户的数据会发生什么变化？

When an advertiser adds a user to their Customer Match list, the user's data is kept confidential and secure. Google employs robust security measures to protect this sensitive information, ensuring it is used only for the intended advertising purpose and not shared indiscriminately. This aligns with privacy principles and data protection regulations. The incorrect options are: "User data will be shared with multiple publishers and platforms" is incorrect because Customer Match data is not broadly shared; it's used privately by the advertiser within Google's ad ecosystem. "User data will be automatically added to other Google products" is incorrect; while Google products are integrated, Customer Match data isn't automatically propagated across all services without explicit user or advertiser action. "User data will be publicly released to all marketers" is fundamentally wrong and a severe privacy violation that Google would never permit.
