In all honesty, this isn't supposed to be as sated above, clients or customers are the ones who should have the right to anonymity, not the company, a company is a public entity (in the case of government owned) or a private entity (in the case of individual owners), even as a private entity, you still owe it to your clients and customers to be as transparent as possible, this is how trust is built between the company and the customers, a company that is claiming right to anonymity to it self on their customers shouldn't be trusted, even for one bit, cus they are indirectly saying they have the right to do whatever pleases them with customers funds.

Customers are the ones taking the risk of trusting your company with their money and also trusting you to pay them in times of winning a bet, so every right to anonymity should be on the customers and not the company.
