I understand what data engineers are supposed to do. But if I was trying to hide what these folks really did for the company I would mislabel them to throw off suspicions. We are talking about Twitter here... Who claims to not have internal fake accounts.
I doubt these data engineers are up to nefarious acts, we know what they were up to, I would bet money the fake accounts, account suspensions and other things Twitter was up to were done at a much higher level than a normal data engineer.
Unfortunately, they for now they will have to suffer because of the actions of their bosses.
