Other arguments include that the name "GNU/Linux" recognizes the role that the free-software movement played in building modern free and open source software communities, that the GNU project played a larger role in developing packages and software for GNU/Linux or Linux distributions, and that using the word "Linux" to refer to the Linux kernel, the operating system and entire distributions of software leads to confusion on the differences about the three. Because of this confusion, legal threats and public relations campaigns apparently directed against the kernel, such as those launched by the SCO Group or the Alexis de Tocqueville Institution (AdTI), have been misinterpreted by many commentators who assume that the whole operating system is being targeted. SCO and the AdTI have even been accused of deliberately exploiting this confusion.
