which of the 5-10~ papers DS published were stolen exactly..?

Industrial-scale national government-sponsored IP theft is one of the most well-documented phenomenon in modern business, and comments like these appear all the time...

Cursory searches provide ample evidence of the ongoing commitment: * The House Homeland Security Committee's February 2025 China Threat Snapshot reports over 60 CCP-linked espionage cases from 2021-2024 across 20 states, with FBI data showing 80% of U.S. economic espionage prosecutions benefiting China and a China nexus in 60% of trade secret thefts, equating to $4,000-6,000 per American family. Rock-solid 2024-2025 examples include Ji Wang's November 2025 conviction for stealing DARPA fiber laser trade secrets worth millions for Chinese entities; Linwei Ding's March 2024 indictment for pilfering Google's AI algorithms to launch a PRC startup; and the Pangang Group's April 2025 Ninth Circuit ruling upholding charges for economic espionage in stealing DuPont's titanium dioxide production secrets.

Each of these cases requires meticulous and expensive documentation to prove, in a court of law with people tasked in defending their innocence.

You can be absolutely sure there is IP theft going on - even if the U.S. can't 'prove' it
