We apologize for any and all problems [our program] has caused to the Grand Theft Auto Online community.
Despite disagreeing with Take-Two's reasoning, the developer agreed with their claims and stopped distribution of OpenIV.
Take-Two Interactive told PCGamer the reason behind why it sent the cease and desist order to OpenIV group saying that the popular GTA Mod tool allowed the creation of malicious mods that resulted in player harassment in GTA Online.
"It was a hard decision, but when any modding activity has been declared illegal, we can't see any possibilities to continue this process, unless top management of Take-Two company makes an official statement about modding, which can be used in court".
Unlike OpenIV, Force Hax was designed for the multiplayer element of GTA V - GTA Online. Nearly immediately, players began complaining that the game's online infrastructure, which uses a simple P2P mesh rather than centralized servers, makes it very hard to cut off hacking tools on a technical level. The developer has chosen to back down from fighting Take-Two on the subject, however. GTA Online has become a major point of pride (and, more importantly, revenue) for Rockstar Games and Take-Two, so it's cracking down on anything that threatens the player experience there. Unfortunately, Take Two Interactive, publisher of GTA V has recently issued a cease and desist letter to the creators of modding tools, including OpenIV, Menyoo and Force Hax. In fact, over the course of the past 30 days, the reviews on Steam for GTA V has been "overwhelmingly negative".
There has also been a reaction on Steam with users leaving negative reviews of the game, criticising Take-Two and the modding policies it has implemented.
In the meantime, a change.org petition has opened to "Save OpenIV".
