One day you're working for a plucky start up. The next you're working for a big name that's stealing tip money.
There's a reason that these companies do what they do. Fraud, breaking the law, and dark patterns are way easier ways to make money than doing so do ethically and legally. Companies either die a hero or live long enough to become a villain.
I'm exaggerating a bit, but realistically the list of ethical tech companies is a lot shorter than the list of unethical ones.
