The possibility that the Generations mod was in jeopardy of being shut down became public the other day (story), and now the other shoe has dropped, as the Generations Main News page has word that this Quake II mod has been "terminated" as a result of correspondence with id Software about its Trademark violations. Thanks The Last Doomer. Word is that the reason they continued this long in violation was the result of a "misunderstanding between [the generations team] and id," but the update also makes it clear that they have not actually been "foxed," that is, id has not specifically asked them to shut down, but rather, this is their voluntary solution to the situation. Here's the part that explains that:

id Software has specifically stated that they are NOT asking us to shut down Generations. Therefore, we are not technically "foxed," as the term goes. But id has set guidelines as to what restrictions we are expected to place on ourselves. Generations, as far as v.98 goes, is in broad, direct, and clear violation of nearly all of these guidelines, in virtually every aspect. In fact, so is every version of Generations that has ever been publicly released. In case you haven't guessed, the Files page is down, and the mirrored downloads will soon be unavailable. In volunteering to remove the files, we hope to avoid any further legal complications with id Software.
