Maybe he was banned because as a developer, he had development tools installed on his machine, which increased the odds of him being labeled as a potential cheater.
Sometimes I even wonder if other hackers could not hack the machine or other players, to install a software that triggers anti-cheat system: it becomes then difficult to lift the ban.
This appears to be the case in Apex Legends: https://old.reddit.com/r/CompetitiveApex/comments/1bhicc6/cl...
Also I wish more "good" hackers were in games, like the guy in GTA Online I ran into once who was shooting me with a money machine gun because Rockstar are greedy assholes.
Eh? Rockstar doesn't force you to buy Shark Cards, and everyone has gotten 11 years worth of DLCs for free. Making in-game money IS an essential part of the game. You also don't have to purchase every single vehicle or other item the game offers.
During my years of playing, I've met only a few cheaters who weren't complete douchebags (though some of them did act that way towards other players). I consider the "good" cheater to be a myth.
Unfortunately, a quick search didn't yield anybody doing math like for the Star Wars: Battlefront (new) debacle.[1][2]
PS: The non-microtransactional design goal in multiplayer games will optimize for more play time.[3] How convenient to offer purchasable shortcuts.
