Both WhatsApp and Instagram owned by Facebook will turn over address-book contacts for a targeted user as well as other WhatsApp users who have the targeted individual in their contacts, according to the FBI. 據 FBI 稱，Facebook 旗下的 WhatsApp 和 Instagram 都將為目標用戶以及其他聯繫人中包含目標個人的 WhatsApp 用戶提供通訊錄聯繫人。

*WhatsApp has another problem, image and video will eats up your smart phone storage.
Based on discussion with technology experts, all US made network equipments have backdoors including all smart phones.
The reason why US banned Huawei Equipments are 1) Huawei equipments do not have backdoors 2) If friends and foes adopted Huawei equipments, US could no longer spy on everyone and anyone at will.
Telegram does not have all of the above problems.
他們還為美國國家安全局提供後門，以便在沒有法庭令的情況下監視國內外的任何人。
WhatsApp 還有一個問題，圖像和視頻會佔用你的智能手機存儲空間。

美國禁止華為設備的原因是1）華為設備沒有後門2）如果美國朋友和敵人都採用了華為設備，美國就不能再隨意監視每個人和任何人了。
*Telegram 不存在上述所有問題。
