Nobody will blow the whistle on whether that's true or not. It's a fact that we can't trust companies like Meta. Not because it's engineers who implement dark patterns or because all the people in a business earn more money if they disregard human or environmental wellbeing but because leadership literally lies to congress, judges, the public, their users and their customers all the freaking time.
And that's great! Similar schemes are still rollin', though, and there are people right here on HN, who could blow the whistle on a great many things that are unethical and corrupt.
