Obviously the employee made some mistakes, he even admits to this. Thats not the point. The point is that Unbabel acted horribly to its employee and acted in bad faith pretty much ever step along the way.

People keep thinking this situation should be about contracts and lawyers and staying silent to help his case in a lawsuit or something. The employee know full well that he is never going to get fully paid for the contract. So he decided to let other people know how bad this company is so others can know about it. This is the best way to punish a company that acts in bad faith.
