Bilibili sent a legal letter to the BiliRoaming open-source project, demanding it stop reverse engineering its non-public APIs, authentication, and paid content protection mechanisms, and delete or revert related code within 2 days. This rare legal action against a reverse-engineering project highlights the escalating tension between platform protection and open-source modifications; it could set a precedent affecting developers and users who rely on such tools. The letter specifically cites actions like hooking playback authentication, rewriting paid bangumi to be viewable, bypassing secure transmission locks, and modifying CDN origin fallback; BiliRoaming is an Xposed module that unblocks Bilibili's regional restrictions for anime shows.
