This article analyzes deplatformization as an implied governance strategy by major tech companies to detoxify the platform ecosystem of radical content while consolidating their power as designers, operators, and governors of that same ecosystem. Deplatformization is different from deplatforming: it entails a systemic effort to push back encroaching radical right-wing platforms to the fringes of the ecosystem by denying them the infrastructural services needed to function online. We identify several deplatformization strategies, using Gab as an example of a platform that survived its relegation and which subsequently tried to build an alternative at the edge of the mainstream ecosystem. Evaluating deplatformization in terms of governance, the question that arises is who is responsible for cleansing the ecosystem: corporations, states, civil society actors, or all three combined? Understanding the implied governance of deplatformization is imperative to assess the higher stakes in future debates concerning Internet governability.

本文将去平台化分析为主要科技公司的一种隐含治理策略，旨在为激进内容的平台生态系统解毒，同时巩固其作为同一生态系统的设计者、运营商和管理者的权力。去平台化与去平台化不同：它需要系统性的努力，通过拒绝提供在线运行所需的基础设施服务，将侵蚀激进的右翼平台推回生态系统的边缘。我们确定了几种去平台化策略，以 Gab 为例，该平台在降级后幸存下来，随后试图在主流生态系统的边缘建立替代方案。从治理的角度评估去平台化，出现的问题是谁负责清理生态系统：公司、国家、民间社会行动者，还是三者结合？理解去平台化的隐含治理对于评估未来有关互联网治理的辩论中的更高风险至关重要。
