What I don't understand how come ideas like this are generated and even passed by the management?
I don't understand how an e-mail like that can even be written. Even if they don't follow through with the action, if that email were to leak it will become a (justified) PR disaster for the company (said company already had a PR disaster a few months before). I might expect a clueless intern to send it out, but not an experienced operations manager. Worse, none of the CS & marketing employees saw anything wrong with that and actually went ahead and posted reviews in their name.
That all said, I was almost going to downvote your comment, but it made remember how much Uber actually has made a business model out of breaking the law in every country they are active in. Move fast and break things became move fast and break the law.
This seems illegal to me, but I really don't know. What are the laws surrounding race-based company promotions/discounts?
