Speculative commentary on US and China buying and withholding zero‑day exploits

Speculative commentary on US and China buying and withholding zero‑day exploits The passage offers a broad, unsubstantiated view of cyber‑weapon procurement by the United States and China but provides no concrete names, dates, transactions, or actionable leads. It repeats known concerns about zero‑day markets without new evidence, limiting investigative usefulness and novelty. Key insights: Mentions that the US and China purchase zero‑day vulnerabilities for undisclosed use.; Suggests a hypothetical "buy‑and‑publish" model to improve security, but notes it is not practiced.; Cites Dan Geer’s 2014 speech on cybersecurity as realpolitik.
