The Grand Theft Auto modding community worked under this response to continue to build out mods and other content within the bounds set by Take-Two.[1] In February 2021, Take-Two issued a Digital Millennium Copyright Act (DMCA) takedown of two projects hosted at GitHub that had reverse-engineered the game engines for Grand Theft Auto III and Vice City, asserting that such reversing engineering was disallowed by the game's EULA.[119] On 10 June 2021, the project developers filed a counter-notice; per DMCA rules regarding disputes, the source code was restored after two weeks.[120] Take-Two CEO Strauss Zelnick stated the company has a "pretty flexible" view on user mods, asserting that "if the economy is threatened, or if there's bad behaviour, and we know how to define that, then we would issue a takedown notice".[121] However, the company proceeded to continue to file a lawsuit in California against the programmers behind this effort in September 2021, asserting that the programmers "are well aware that they do not possess the right to copy, adapt, or distribute derivative GTA source code, or the audiovisual elements of the games, and that doing so constitutes copyright infringement."[122] As part of the lawsuit, Take Two issued another takedown notice to GitHub to remove the mods in October 2021.[123] The modders, in their legal reply, asserted that use of the assets were within fair use, as the reversed engineered versions were transformative in nature and as Rockstar nor Take Two had issued any updates for years, did not harm the commercial prospects of the games.[124]
