Lol what is there to envy dude...like really. I'm not saying this out of disdain of the guy, I gave him props. What I'm saying is you don't understand the entire situation. I'm trying to explain to you why R* and TakeTwo might not be impressed but instead upset that they had such a huge flaw in their system. I'm saying this to inform those not familiar with the situation why this happened.
On top of that, you don't understand the context of those videos. THATS NOT HIM inputting codes and testing the game. Those are videos made by the R* staff displaying and testing certain things in the game.
Again they have a work from home system. So the developers are testing things and sending them off to their peers and management. He ripped those videos off their server.
The fact that you didn't know this, and actually thought this kid was actually play testing and coding in a game engine he has no clue about emphasize how you have very little understanding of the situation. Which isn't an insult to you, because a lot of ppl have no idea how these things work.
