I am surprised engineers have not been leaking information like this more. Like waaay waaay more. Especially youtube, due to its reach and history of adpocalypse 1.0, 2.0 and others. Google as whole and the big daddy - Facebook, who has been proven to run psychological experiments on selected samples of population and scamming advertisers. I do not buy that NDA bullshit. That has nothing to do with ethics. I am frankly quite disappointed in people working in IT nowadays that they just keep on grinding with these manipulative and exploitative companies and their policies and agendas. I actually have way more respect for an engineer whom is writing code for ballistic missiles than people working in these big tech companies. Sure, the salary is nice, but how much does it take to sell your soul? I am not being spiritual or religious here but rather looking at it from one own's psyche point of view and long term health effects of doing work like this, despite the big bucks at the end of the month.
