3Q War / 3Q 大战

Overview

The 3Q War / 3Q 大战 is the Qihoo 360 versus Tencent conflict summarized in No.216 ⚔️ 「十步杀一人」：红衣大炮周鸿祎的三十年全面战争史 | 中国互联网故事 27. The episode treats it as a public crisis where security software, instant messaging, platform power, and user choice were turned into weapons.

Current Profile

The event is the clearest case in this source for Chinese Internet Platform Wars / 中文互联网平台战争: competitors with privileged access to user desktops could escalate product conflict into deletion, blocking, public accusation, and “choose one” pressure.
