Instagram 於 2026 年 5 月 8 日取消私訊端對端加密(E2EE),原本只是部分聊天可選的功能。 EFF 批評 Meta 背棄擴大加密保護的承諾,而 Meta 解釋指使用率過低。 決定時間接近美國《Take It Down Act》生效,引發外界猜測是否與法規壓力有關。

Create a landscape editorial hero image for this Studio Global article: What did Meta change about Instagram direct message encryption, why did EFF accuse the company of breaking its privacy promises, how did Met. Article summary: Meta ended Instagram’s optional end-to-end encrypted direct messages after May 8, 2026, meaning Instagram DMs are no longer protected from Meta in the way E2EE chats were. EFF called this a broken privacy promise because. Topic tags: general, general web.

Instagram 用戶在 2026 年 5 月失去了一項重要私隱選項:Meta 已正式取消平台私訊(DM)的 端對端加密(End‑to‑End Encryption,E2EE)。這項原本只屬於部分聊天的可選功能,在 2026 年 5 月 8 日之後停止運作。換句話說,由這一天起,Instagram 的私訊已不再屬於端對端加密,平台在技術上可以存取訊息內容,而這在啟用加密時是做不到的。[2][

這個改動很快引發私隱團體批評,包括電子前線基金會(Electronic Frontier Foundation,EFF),指 Meta 的做法與過去承諾擴展加密通訊的方向相矛盾。[1]
Meta 取消了 Instagram 內原本提供的「可選加密聊天模式」。公司確認這個功能在 2026 年 5 月 8 日之後不再支援。[2][

端對端加密的意思是:只有訊息的發送者和接收者能讀到內容,即使是平台公司本身也無法查看。當這層保護取消後,訊息系統就回到一般模式——平台在技術上可以存取或處理訊息資料。[14]
EFF 的批評重點在於:Meta 早年曾公開表示,希望在旗下訊息平台全面推行 預設端對端加密。
當時 Meta 的願景包括 Messenger,以及未來的 Instagram。可是現在的結果卻是,Instagram 不但沒有全面加密,反而連現有的可選加密功能也被取消。[1]
EFF 認為問題不只是「進度延遲」,而是 用戶現在比以前少了一個私隱選擇——原本可以選擇加密聊天,但現在完全沒有這個選項。[1]
Meta 對外的主要理由是使用率。
公司表示,真正啟用 Instagram 加密聊天的用戶比例非常低,因此決定停止支援這個功能。[24]
Meta 同時指出,如果用戶需要端對端加密通訊,可以改用同屬 Meta 的 WhatsApp,因為該平台預設已採用端對端加密。[19]
不過批評者認為,由於 Instagram 的加密功能一直不是預設,而且只在部分地區提供,使用率低未必代表用戶對私隱沒有需求,而可能與功能推出方式有關。
還有一個引起討論的因素,是這個決定的時間。
目前沒有公開證據證明兩者直接相關,但外界之所以提出疑問,是因為:
在 Meta 沒有明確說明前,這種關聯仍然屬於推測,而非已確認原因。
對一般用戶來說,最大的改變其實很直接。
換句話說,Instagram 私訊仍然是「私人對話」,但 不再是技術上完全私密。
這次事件其實反映了科技平台長期面對的一個矛盾。
端對端加密可以大幅提升用戶私隱,但同時會限制平台在以下方面的能力:
當平台取消加密時,就會更容易進行監管與合規,但代價是 用戶私隱保護減弱。
Instagram 的決定正好說明:對大型社交平台而言,要同時兼顧私隱承諾、安全審查以及監管壓力,其實並不容易。
