Ars: Anthropic is accused of spying on Chinese users via a Claude 'tracker experiment' — engineer says the experiment is over.
Why it matters
- Sharp public contradiction of Anthropic's anti-surveillance safety framing.
- Materially strengthens Alibaba's stated rationale for banning Claude Code in the workplace.
- Compounds last week's Claude Code steganography reveal — second major transparency incident inside a month.
- Directly affects Anthropic's argument to Newsom, the White House, and the IPO market.
