Meta 在 2026 年 5 月 8 日停止 Instagram 私訊的可選端對端加密功能。 電子前哨基金會(EFF)批評此舉違背 Meta 過去推動加密通訊的承諾,讓用戶隱私選擇變少。 Meta 表示功能使用率很低,但時間點接近美國《Take It Down Act》生效,也引發外界猜測。

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.

2026 年 5 月,Instagram 用戶失去了一項重要的隱私選項:端對端加密(End‑to‑End Encryption,E2EE)私訊。Meta 已停止支援這項功能,自 2026 年 5 月 8 日 起生效。換句話說,從這一天開始,Instagram 的私訊(DM)不再具備端對端加密保護。 [2][

這項變動迅速引發隱私倡議團體批評,其中電子前哨基金會(Electronic Frontier Foundation,EFF)認為,Meta 此舉與公司過去宣稱要在旗下通訊產品全面推動加密的承諾相互矛盾。 [1]
Meta 取消了 Instagram 原本提供的「可選端對端加密聊天模式」。這個模式並不是預設功能,而是用戶需要手動啟用。公司確認該功能在 2026 年 5 月 8 日之後將完全停止支援。 [2][

這次變更的幾個重點包括:

端對端加密的核心概念是:只有訊息的發送者與接收者可以閱讀內容,即使是平台營運商也無法查看。取消這項保護後,Instagram 私訊回到較傳統的訊息模式,平台在技術上能接觸到訊息資料。 [14]
EFF 的批評集中在 Meta 過去的公開表態。
多年來,Meta 一直表示希望在其通訊產品生態系(例如 Messenger、WhatsApp,以及最終的 Instagram)中 全面推動端對端加密。然而在 Instagram 上,不僅沒有推向預設加密,現在甚至把原本存在的可選加密功能也取消。 [1]
在隱私倡議者看來,問題不只是「進度延後」,而是 用戶可選的隱私保護反而變少了。過去至少能自行開啟加密,如今這個選項也消失了。 [1]
Meta 對外的官方解釋相對簡單:很少人使用這項功能。
公司表示,只有極少數 Instagram 用戶選擇啟用加密聊天,因此決定停止維護該功能。 [24]
Meta 同時指出,旗下另一個通訊平台 WhatsApp 預設就提供端對端加密,如果用戶希望進行高度隱私的對話,可以改用該服務。 [19]
不過批評者也指出,由於 Instagram 的加密功能一直不是預設開啟,而且只在部分地區推出,低使用率可能與功能設計與推廣方式有關,而不一定代表用戶沒有需求。
另一個引發討論的,是政策時間點。
目前沒有公開證據顯示這項法律直接導致 Meta 的決策。不過外界仍提出一些推測,例如:
由於 Meta 並未正式將兩者連結,這種關聯仍屬推測,而非已確認的原因。
對一般使用者而言,這項變動最大的影響是對「私訊隱私」的認知需要調整。
簡單來說:Instagram 私訊仍然是方便的社交工具,但不再能被視為對平台本身完全保密的通訊方式。
這次事件也再次凸顯大型社群平台面臨的長期難題。
端對端加密能提供更強的用戶隱私,但同時也會限制平台在以下方面的能力:內容審核、調查濫用行為、以及快速回應法律要求。取消加密則讓平台更容易管理與合規,但代價是用戶隱私保護降低。
Instagram 的決定,正好反映了社群平台在 隱私保護、內容安全與監管壓力之間持續拉鋸的現實。
