I watched China ban my whole category. My app can't be banned the same way
China just deleted millions of AI companions. The off switch was the business model
On July 15, the biggest AI companion features in China ceased to exist. Doubao (about 345M MAU), Qwen (about 166M), Tencent's Yuanbao: all shut down their user-built companion personas. Tencent did it June 30. Qwen switched off agents July 10, with no migration path - configs and chat histories gone. Doubao gave users until October 15 to screenshot what was left.
The reason was a regulation: China's Interim Measures for AI Anthropomorphic Interaction Services, effective July 15. It bans virtual partners for minors and design that induces emotional dependence. Adults can still use AI companions in China. The companies just decided the compliance cost was higher than the deletion cost.
Users lost real things. One woman exchanged roughly 700,000 words with her AI boyfriend over two years and got no goodbye. She told AP it felt like being separated by her parents.
Here is the part I cannot stop thinking about as someone who builds an AI companion: every one of those shutdowns was a remote switch.
Doubao's companions lived on ByteDance's servers. The characters, the memories, the chat history - all in a data center someone else owns. When the regulator spoke, the company flipped a switch and the product vanished. Not because the users did anything wrong. Because the runtime was never theirs.
I build Local Waifu, a desktop AI companion. The model runs on your machine. Memory, voice, image generation - local. There is no account, no server between the user and the companion. That means there is no switch for anyone to flip. A government can restrict distribution channels in its jurisdiction - I don't pretend otherwise. But nobody can reach into a data center and turn off a runtime that is sitting on your hard drive.
The lesson is bigger than AI companions. If your product's value lives on a server you rent, your business model includes a kill switch you don't own. The platform can change terms, the regulator can act, the vendor can fold - and the relationship your users built evaporates with it.

Build like the off switch is not yours. Because one day it will not be.
