In June 2002, the AdTI published a report, quickly pulled under the argument that it was a draft version, which contained criticism of the copyleft model and the GNU General Public License. A May 2002 press release for the report stated that it would contain arguments suggesting that governments could be threatened by hackers and terrorists (who could study potential vulnerabilities due to source availability) if it used open source software. However, the draft contained no references to these topics. Open Source Initiative (OSI) founder Bruce Perens felt that the report had "Microsoft's paws all over ". Microsoft argued that its funding was for AdTI's operations as a whole, and not relevant to any specific research by the organization.
