    AGPL 與大 SaaS 時代授權的逆襲 - RSChiang === ###### tags: `COSCUP2022` `zh-tw` `Skilled` `主議程軌` {%hackmd fr80qNy7Q8ODJHiCg39n6g %} > 請從這裡開始 {%speakerdeck rschiang/the-license-strikes-back-agpl-and-cloud-targeting-licenses-in-the-era-of-saas %} <!-- 簡報稍後上傳 --> ## 為什麼會講到 AGPL? - Hector Martin 在 Twitter 上抱怨大家都沒有遵守 AGPL 的規定 > 如果想打筆戰有不想浪費時間,就把內容拿去 COSCUP 投稿 > [name=RSChiang, COSCUP 2022] ## 迅速複習一下授權光譜 ## GPL 3.0 [ref](https://www.gnu.org/licenses/gpl-3.0.zh-tw.html) ## 四大自由 [ref](https://www.gnu.org/philosophy/free-sw.zh-tw.html) - 零:不限目的,隨心所欲執行程式的自由 - 一:研究程式運作方式、並隨心所欲修改執行的智遊 - 二:散步拷貝幫助別人的自由 - 三:將你修改過後的版本散布給他人的自由 ## xkcd.com Dependency https://xkcd.com/2347/ ![](https://i.imgur.com/bUx5xMf.png =300x) ## What Heartbleed Taught the Tech World - 基礎建設的人力是否投入不足? - 僅有少數的個人開發者在維護 - openSSL 的 Heartbleed 案例 ## Open source dev, who work for free are discorvering they have power - 當大家逐漸採用開源軟體,這些開源貢獻者...變得有點像是為大公司作嫁衣? - 成果被無償的取用 ## AGPL - AGPL: "Affero" GPL - 改了什麼? - 把 AGPL 跟 GPL 做 diff 比較 相較於 GPL,AGPL 修改了: - 授權條款名稱 GPL -> AGPL - 前言(訂定原油替換成對應敘述) - 第 13 款「遠端網路互動」條款:如果會被使用者透過網路互動,需要讓使用者可以取得 source? - 刪除末尾關於 LGPL 的說明 ## AGPL 到底哪裡不自由 - 第 13 條遠端網路互動如何解釋? - email 算嗎? - 雲端服務如何定義目的碼與對應原始碼 - JIT 編出來的 code? - Cache - 外加條款的效力? -> Neo4j v. Graph Foundation - 為什麼撰寫 license 的人可以拘束我的使用方式 - 契約定性與約束力問題 - 授權條款 or 契約? - 拘束力到底到什麼程度? 有些公司只想要得到開源的美名,但實際沒有開源出來。 ## 延伸授權條款 - SSPL (Server Side Public License) - 修改自 AGPL,針對 PaaS、SaaS 做額外規範 - 無論有無修改,若透過網路提供服務,都有提供原始碼的義務 - 提供原始碼的範圍包含管理、備份、網頁介面 約略等於 整套平台原始碼 - (A)GPL 是否允許此種衍生授權? - SSPL 本質上是否仍為自由軟體? - Anti 996 License - 由 UIUC 法學院與資訊學院的研究生發起 - 訴求正視中國國內軟體工程師過勞(「996」)議題 - MIT License 加上"被授權法人需遵守勞動法規" - 加上特定限制,本質上是否仍為開源軟體? ## 爭議的答案 > 判例過少,仍待學界與法界形成完整學說 - GPL 有少數判例、AGPL 更少 ## 後開源時代:作為社群,我們想選擇的價值是什麼? - ~~聽起來又可以講一個 talk~~ ## Q&A > dual-license (community & enterprise) 是否 OK? AGPL AGPL 一個可能的疑問,是會不會造成參與 AGPL 開源專案的貢獻者到最後只是為授權者服務?
