Reaction to NGSCB after its unveiling by "Newsweek" was largely negative. While its security features were praised, critics contended that NGSCB could be used to impose restrictions on users; lock-out competing software vendors; and undermine fair use rights and open source software such as Linux. Microsoft's characterization of NGSCB as a security technology was subject to criticism as its origin focused on DRM. NGSCB's announcement occurred only a few years after Microsoft was accused of anticompetitive practices during the "United States v. Microsoft Corporation" antitrust case, a detail which called the company's intentions for the technology into question—NGSCB was regarded as an effort by the company to maintain its dominance in the personal computing industry. The notion of a "Trusted Windows" architecture—one that implied Windows itself was untrustworthy—would also be a source of contention within the company itself.
