disgruntled programmers are a real thing. one guy even snuck in a hidden code about how stupid his boss was and everyone at nintendo? was an idoit. i wish i could remember the name of the game. plenty of other stories about what programmers do when they feel slighted.
Never said they aren`t. But it is a really long shot to think that all the cheats this game has or will have, come from disgruntled employees. Not when we have solid evidence for sh*t programming and almost no testing - like duping, half loading, mission prices, restart buttons, invisible because game didn`t load properly. Those are all bugs, not intended mechanics.
It is smarter to believe that some smart folks found bigger holes in coding than to blame all the worst things on some mystical Rockstar employee.
