Look at it this way people, he's trying to motivate other devs to find the way themselves so they may do it again some other time. If he's the only one capable of doing it and he really does leave the scene, what are we left with?
I'm sure there are some underground devs who are capable of doing the same thing but what about the others? (not saying other devs are useless ofc, I appreciate your work people)
And if this IS true than stop *****ing about him "showing but not releasing" because if he didn't show ****, you would all still be saying to 3.56+ people "There will never be better than a 3.55 CFW, downgrade or GTFO". At least now there is some hope...
Also, maybe he does intend to release this anonymously but acts like he's not in order to seem innocent when he does, and if he doesn't, I totally understand because there are so many ungrateful *******s who keep yelling around "WHER IZ 3.73 CFW!1!.. U SUCK DEVZ"..
So in the end if this is true, i support him whether he releases or not (although if he does we probably won't know it's him)
