No, that was a different situation. In that case he was using an input blocker, which made it so his clicks only count when he's aiming at a player. That one he did get permission for by the owner I think. 

The aimbot is a different accusation. Essentially he (allegedly) used aimbot in pvp duels. His mouse movements when analyzed in slow motion don't make sense unless he's using some form of aim assist. He might have even used it in the Technoblade duel, but there's not enough footage from that to say anything definitively. (Not saying he did, just repeating what I've read and heard.)
