From some point in time which I can't quite recall and ain't gonna go looking for (pretty sure it was three months ago) wolves brought this tool into its first working state, at this point only wolves were using it, pretty sure already here they had asked the dev team whether it was ok though. Later on at some point in time along with improvements into the product it was also introduced to more testers, which was arguably bad as the testers purely consisted of the eastern carebear bloc and Hospitaller. The bloc have used it for quite some time and the product first became known to the public after it was given to nordmen and they showed the thing in an argument with Gingerpussy, I'm pretty sure they were quitting or something at that time and Kinngrimm gave it to the them to make them stay, ain't sure though so do not take this as fact. Now, after the entire shitstorm of UIF and random people being pissed at eastern and wolves for using the "3rd party program giving a gigantic advantage" wolves finally released the product to the public in this (

Basically to sum it all up I'd say that the eastern carebear bloc developed and used third party programs to gain an advantage that may or may not be severe, however wolves did intend on eventually giving it to everyone, and Kinngrimm says that the reason he only gave it to eastern was that he needed testers he trusted.
